1. 01 Agra Fort

   India · 1.1 km from Agra27.180° N 78.021° E

   • UNESCO World Heritage

   

   Agra Fort is the walled citadel from which the Mughal emperors ruled northern India for most of a century, and it is the key to understanding everything else in Agra, the Taj Mahal included. A fort stood on this bend of the Yamuna long before the Mughals, but the present one is essentially the creation of Akbar, who ordered the old brick stronghold rebuilt in 1565. Work continued until 1573: a brick core faced with red sandstone brought from the Dholpur area of Rajasthan, enclosing a half-moon plan whose straight side faces the river. It remained the principal residence of the dynasty until 1638, when Shah Jahan moved the capital to his new city of Shahjahanabad in Delhi.

   Did you know? Jahangir ordered a golden Chain of Justice with 60 bells, stretched from the fort's Shah Burj to a post on the Yamuna bank, so petitioners could summon the emperor.

2. 02 Tsarevets

   Царевец

   Bulgaria · 0.4 km from Veliko Tarnovo43.083° N 25.653° E

   

   For two centuries the rocky hill of Tsarevets was the beating heart of the Second Bulgarian Empire. Between 1185 and 1393 it served as the chief stronghold of the capital Tarnovo, sheltering both the royal palace and the seat of the Bulgarian patriarch. People had lived here since the second millennium BC, and an early Byzantine town stood on the summit before the Bulgarian fortress rose on top of it in the 12th century.

   Did you know? In 1300 Patriarch Joachim III was put to death at Execution Rock above the Yantra on the orders of Tsar Theodore Svetoslav.

3. 03 Nesvizh Castle

   Нясвіжскі палацава-паркавы комплекс

   Belarus53.223° N 26.692° E

   • UNESCO World Heritage

   

   Nesvizh Castle was the principal seat of the Radziwiłłs, the wealthiest magnate family of the Grand Duchy of Lithuania, and it is the grandest aristocratic residence surviving in Belarus. Its yellow Baroque ranges close around a courtyard entered through a gatehouse tower, with ponds and landscaped parkland around it. Together with the Corpus Christi Church in the town it was inscribed as a World Heritage Site in 2005, recognised for its influence on the architecture of Central and Eastern Europe.

   Did you know? Nesvizh had its own cannon foundry, the first in Belarus, which cast its first series of guns in 1576.

4. 04 Belém Tower

   Torre de Belém

   Portugal · 7 km from Lisbon38.691° N 9.216° W

   • UNESCO World Heritage

   

   The Tower of Saint Vincent, as it was officially named, was built in the 1510s and finished in 1519 to guard the mouth of the Tagus, completing a ring of river defences first planned by King John II and carried out by Manuel I. It stood on a basalt outcrop just off the Lisbon shore, and ships returning from India passed beneath it before reaching the city. The popular story that the 1755 earthquake shifted the river away from it is wrong; the tower was always close to the bank, and land reclaimed over the centuries simply caught up with it.

   Did you know? For about 250 years, from 1580 to 1830, the dark vaults of the bastion served as a prison.

5. 05 Palamidi

   Παλαμήδι

   Greece · 38 km from Tripoli37.562° N 22.804° E

   

   Palamidi crowns a 216-metre hill above Nafplio, and it is a textbook baroque fortress. The Venetians, who held the Peloponnese for a second time between 1686 and 1715, built it in a remarkably short burst of work completed in 1714, to plans by the engineer Antonio Giancix and with the French military engineer Pierre de la Salle in charge of construction. Its bastions are strung out along the crest of the hill.

   Did you know? The climb from the old town is famed as 999 steps, but the staircase actually has 857.

6. 06 Khotyn Fortress

   Хотинська фортеця

   Ukraine · 19.1 km from Kamianets-Podilskyi48.522° N 26.498° E

   

   Khotyn Fortress rises from a rocky shelf on the high right bank of the Dniester in the town of Khotyn, in Ukraine's Chernivtsi Oblast. The river crossing here lay on old trade routes between the Baltic, Kyiv and the Black Sea, and the site has been fortified since the time of Kievan Rus', when an earthen mound with wooden walls guarded the crossing and a first, small stone building stood where the northern tower is now. Between 1250 and 1264 Prince Danylo of Halych and his son Lev rebuilt it in stone, but the fortress that survives is essentially Moldavian.

   Did you know? In the 1621 Battle of Khotyn, a Commonwealth and Cossack force of about 50,000 held off an Ottoman army estimated at roughly 100,000.

7. 07 Ivangorod Fortress

   Russia · 2.7 km from Narva59.375° N 28.208° E

   

   Few places on earth stage a medieval standoff as literally as the Narva River. On its west bank stands Hermann Castle in Estonia; on the east bank, barely a stone's throw away, rises Ivangorod Fortress in Russia. Grand Prince Ivan III of Moscow had it raised in a single summer in 1492, on a hill called Maiden's Mount, as a deliberate answer to the knights across the water and as a claim on Muscovy's route to the Baltic. The town that grew up around it still carries his name.

   Did you know? In 1496, just four years after it was built, a Swedish force of about 5,000 men on 70 ships stormed the fortress in no more than seven hours.

8. 08 Fort Boyard

   France · 19.2 km from La Rochelle46.000° N 1.214° W

   

   Fort Boyard took fifty-six years to build and was obsolete within two. Construction started in 1801 under Napoleon, aimed at closing a gap in French coastal defences between two islands off La Rochelle, but the project stalled in 1809 and sat unfinished for nearly three decades before Louis Philippe I restarted it in 1837 over renewed friction with Britain. When it was finally completed in 1857, artillery range had moved on so far in the intervening decades that the gap the fort was built to cover no longer needed covering — the fort that took two generations to finish was militarily pointless by the time it could fire a shot.

   Did you know? According to a famous story, Vauban told Louis XIV it would be easier to seize the Moon with one's teeth than to build a fort here.

9. 09 Castillo San Felipe del Morro

   United States · 3.5 km from San Juan18.471° N 66.124° W

   

   Castillo San Felipe del Morro rises in six levels from the Atlantic at the northwestern tip of the islet of Old San Juan, a mass of sandstone walls, ramps, gun batteries and sentry boxes climbing some 43 metres from the surf to the headland. For three and a half centuries it guarded the narrow entrance to San Juan Bay, the harbour of a city Spain regarded as a key to its Caribbean empire.

   Did you know? In March 1915 a gunner at El Morro fired on the German freighter Odenwald as it left without clearance, often called the first American shots of World War I.

10. 10 Belogradchik Fortress

    Белоградчишка крепост

    Bulgaria43.623° N 22.677° E

    

    Belogradchik Fortress is one of those places where nature did half the engineering. On the northern slopes of the Balkan Mountains, the Romans used the famous Belogradchik Rocks — natural stone pillars up to 70 metres high — as ready-made walls, building masonry only on the northwest and southeast sides where the rock left gaps. The result is a stronghold that seems to grow out of a stone forest, and it is among the best preserved in Bulgaria.

    Did you know? Locals simply call the fortress Kaleto, from the Turkish word kale, meaning fortress.

11. 11 Cité de Carcassonne

    France43.206° N 2.364° E

    • UNESCO World Heritage

    

    The Cité de Carcassonne is the most complete fortified medieval town in Europe — a hilltop enclosed by two concentric rings of walls, about 3 km in total, punctuated by 52 towers, on the right bank of the Aude above the modern city. UNESCO inscribed it in 1997 as an exceptional example of a medieval fortress town, and also for the way it was saved in the 19th century.

    Did you know? The board game Carcassonne, released in 2000, was created by Klaus-Jürgen Wrede after the landscape around the city inspired him.

12. 12 Lovrijenac

    Croatia · 2.5 km from Dubrovnik42.641° N 18.104° E

    

    Fort Lovrijenac, the fortress of St Lawrence, stands on a sheer rock 37 metres above the sea just outside Dubrovnik's western walls, and it earned the nickname "Dubrovnik's Gibraltar". From this perch it commands both the approach by sea and the land road to the Pile Gate. The city's chronicles tell a proud story: when Venice planned to build its own fort on the same rock to keep the city under control, the citizens raced ahead and raised theirs in just three months, so the Venetian ships loaded with building material had to sail home. Chroniclers date the fort to the early 11th century, though the first written record comes from 1301, when the city council appointed its commander.

    Did you know? In Game of Thrones the fort stood in for the Red Keep of King's Landing, and many of the Red Keep scenes were shot inside its walls.

13. 13 Pskov Krom

    Russia · 1 km from Pskov57.821° N 28.329° E

    

    The Pskov Krom is the kremlin at the very origin of the city: a narrow, high promontory where the Pskova River flows into the Velikaya, fortified since at least the 8th century and first named in the chronicles as the "Krom" in 1113. The ensemble covers the Krom itself, about 3.5 hectares, and the adjoining Dovmont's Town, about 1.5 hectares, named after the 13th-century prince who walled it. In the days of the Pskov Republic, from the 14th to the early 16th century, this was the political and spiritual core of the land: the veche assembly met on the square beside the cathedral, next to the kremlin's storehouses.

14. 14 Fasil Ghebbi

    Ethiopia · 1.1 km from Gondar12.608° N 37.470° E

    • UNESCO World Heritage

    

    Fasil Ghebbi is a castle compound unlike anything else in Africa: a walled royal enclosure in the middle of Gondar, filled with palaces built by successive Ethiopian emperors. Until the seventeenth century the emperors ruled from moving camps, living in tents as they travelled across their realm. Emperor Fasilides broke with that tradition, made Gondar his fixed capital, and in the 1640s began the great stone castle that gave the compound its name — ghebbi is Amharic for an enclosure. A Yemeni envoy who saw it in 1648 described it as one of the most marvellous buildings he had seen, and named its architect as an Indian, Abdal Kerim. Later palaces were the work of an Ethiopian architect, Walda Giyorgis, and much of the stonework was done by the Beta Israel, Ethiopian Jewish craftsmen.

    Did you know? An Armenian envoy, Khoja Murad, visited the palace in 1696 and claimed that at least 80 royal children were running freely around the compound.

15. 15 Peter and Paul Fortress

    Russia · 1 km from Saint Petersburg59.950° N 30.317° E

    • UNESCO World Heritage

    

    Saint Petersburg began here. On 27 May 1703 (16 May Old Style) Peter the Great founded a fortress on Hare Island on the Neva, and the city counts its birthday from that day. The earthen defences were soon replaced in stone to designs by the Swiss-Italian architect Domenico Trezzini, and work went on from 1706 to 1740. The result is a six-bastion star fortress; the bastions are named after Peter himself and five of his closest associates, among them Menshikov, Naryshkin and Trubetskoy. Paradoxically, a fortress built to guard Russia's new outlet to the Baltic never fired in battle.

    Did you know? Peter the Great's own son, Tsarevich Alexei, was imprisoned in the fortress in 1718 and died there that year.

16. 16 Citadelle Laferrière

    Haiti · 20.8 km from Cap-Haïtien19.574° N 72.244° W

    • UNESCO World Heritage

    

    The Citadelle Laferrière is the largest fortress in Haiti and one of the largest in the Americas, and it was built by a nation that had only just freed itself. Henri Christophe, a leader of the Haitian Revolution, commissioned it in 1805, the year after independence from France, as the keystone of a defence system against a French return that never came. Tens of thousands of former slaves laboured on it until its completion in 1820; by some estimates the work cost up to 20,000 lives. Christophe, who later declared himself king of northern Haiti, is buried inside: after his suicide in 1820, followers covered his body in quicklime and sealed it in one of the courtyards.

    Did you know? The mortar binding the walls is said to have included quicklime, molasses, the blood of local cows and goats, and boiled cow hooves.

17. 17 Qazan Kremlin

    Russia · 5.2 km from Kazan55.797° N 49.107° E

    • UNESCO World Heritage

    

    The white-walled citadel of Kazan is where two worlds meet. It stands on the site of the fortress of the Kazan khans, which Ivan the Terrible's army captured in 1552; the tsar then had it rebuilt in stone by Pskov masters Postnik Yakovlev and Ivan Shiryay, known as Barma. Their Annunciation Cathedral, built between 1554 and 1562 from local pale sandstone rather than brick, is the oldest building inside. The walls and towers themselves date from the 16th and 17th centuries, with later renovations, and the Spasskaya Tower at the southern end still serves as the main gate.

    Did you know? Postnik Yakovlev and Barma, the Pskov masters who rebuilt the kremlin in stone, are the same builders credited with St Basil's Cathedral in Moscow.

18. 18 Bahla Fort

    Oman · 24 km from Nizwa22.964° N 57.301° E

    • UNESCO World Heritage

    

    Bahla Fort rises from the oasis of Bahla at the foot of the Jebel Akhdar highlands, one of four great historic forts in the region and the first place in Oman to be added to the UNESCO World Heritage list, in 1987. It is believed to have been built between the 12th and 15th centuries by the Banu Nebhan, a tribe that controlled the frankincense trade, and it is a monument to building in earth: its towers and walls are made of mud brick with straw, on stone foundations.

    Did you know? Bahla was a seat of the Nabhani dynasty, first as a second capital after Nizwa and then, from the mid-16th century to 1624, as its main capital.

19. 19 Kremlin

    Russia · 0.4 km from Moscow55.752° N 37.618° E

    • UNESCO World Heritage

    

    The Moscow Kremlin is a walled citadel on Borovitsky Hill, where the Neglinnaya once flowed into the Moskva River. It has been the seat of Russian power, with interruptions, for most of the last seven centuries. A timber fort stood here in the 12th century. Ivan I rebuilt it in oak in 1339, and Dmitry Donskoy replaced that with white limestone in the 1360s. The red-brick walls and towers seen today date from 1485–1495. They were built for Ivan III by Italian engineers, above all Pietro Antonio Solari, whose name is still carved in Latin over the Spassky Gate. The wall runs for about 2.2 km around an irregular triangle, between 5 and 19 metres high depending on the ground, and has twenty towers. The tallest, the Troitskaya, reaches 80 metres. The illuminated stars on several towers replaced golden eagles in Soviet times.

    Did you know? The 202-tonne Tsar Bell has never rung: water thrown on it during a 1737 fire cracked it and broke off a slab weighing over 10 tonnes.

20. 20 Ark of Bukhara

    Uzbekistan · 1.7 km from Bukhara39.778° N 64.410° E

    

    The Ark is Bukhara's citadel: an artificial hill with steep earthen walls 16 to 20 metres high that rises out of the flat city like a ship. Archaeologists have found some twenty metres of earlier layers beneath it, the remains of fortresses built and destroyed again and again, and by around 500 CE it was already the seat of local rulers. For most of its history the Ark was less a barracks than a walled town of its own, where the ruler, his ministers, officials, soldiers and servants lived, worked and kept the treasury and the prison.

    Did you know? A large leather whip once hung on one of the Ark's walls as a symbol of the emir's power over his subjects.

21. 21 Bat, Al-Khutm and Al-Ayn archaeological sites

    Oman · 23.9 km from Ibri23.270° N 56.745° E

    • UNESCO World Heritage

    

    On the rocky ridges above the village of Bat, in the interior of northwestern Oman, dozens of stone tombs shaped like beehives stand against the sky, built some five thousand years ago. Together with the nearby sites of Al-Khutm and Al-Ayn, they form one of the most complete and best-preserved groups of settlements and burial grounds of the third millennium BC anywhere in the world, and in 1988 they became Oman's second UNESCO World Heritage Site, after Bahla Fort.

    Did you know? The cemetery at Bat holds roughly 400 tombs and is considered the largest and best-preserved Bronze Age cemetery in south-eastern Arabia.

22. 22 Castillo de San Pedro de la Roca

    Cuba · 8.1 km from Santiago de Cuba19.969° N 75.870° W

    • UNESCO World Heritage

    

    The Castillo de San Pedro de la Roca, usually called El Morro, is a fortress built in tiers down a rocky headland at the mouth of the bay of Santiago de Cuba. UNESCO inscribed it in 1997 as the most complete and best preserved example of Spanish-American military architecture, and its stacked platforms, bastions and stairways dropping towards the sea make it one of the most dramatic colonial forts in the Caribbean.

    Did you know? Seen from above, the fortress's stepped terraces form the shape of a spearhead aimed at the open sea.

23. 23 Lahore Fort

    Pakistan · 4.8 km from Lahore31.590° N 74.310° E

    • UNESCO World Heritage

    

    The Lahore Fort, the Shahi Qila, occupies the northern corner of Lahore's walled city and covers more than 20 hectares. A mud fort stood here by the 11th century, and it was destroyed and rebuilt several times — by the Mongols in 1241, by Timur in 1398 — before the Mughal emperor Akbar replaced it in brick in 1566 to guard the empire's northwestern frontier. What makes it special is that the complex was then almost entirely rebuilt during the 17th century, when the Mughal court was at its most lavish, so the fort is effectively a catalogue of Mughal taste at its peak.

    Did you know? In 1959 excavators found a gold coin of Mahmud of Ghazni dated 1025 CE buried about 25 feet below the fort's surface.

24. 24 Kuélap

    Peru · 21.6 km from Chachapoyas6.418° S 77.923° W

    

    Kuélap rides the crest of a limestone ridge at about 3,000 metres above the Utcubamba valley in the cloud-forest country of northern Peru. It was built by the Chachapoya, a people who lived in these steep, wet Andean valleys long before the Inca reached them. People were already living on the ridge in the fifth century, but most of what stands today was raised between about 900 and 1100. The result is a walled settlement nearly 600 metres long and up to 110 metres wide, wrapped in a wall of finely dressed limestone blocks that rises 10 to 20 metres high in places, so that from the valley it reads less like a town than like a great stone ship moored on the mountain.

    Did you know? Of the 421 buildings inside the walls, only five are rectangular; every other structure on the ridge is round.

25. 25 Fatehpur Sikri

    India · 20.1 km from Bharatpur27.091° N 77.661° E

    • UNESCO World Heritage

    

    Fatehpur Sikri was an imperial capital for barely fourteen years. The Mughal emperor Akbar had waited a long time for an heir, and when his son Salim, the future Jahangir, was born in the village of Sikri in 1569, he credited the prediction of the Sufi saint Shaikh Salim Chishti, who lived there. Akbar first built a great mosque around the saint's hermitage and then, from 1571, a walled city and palace on the ridge beside it. After his conquest of Gujarat in 1573 it took the name Fatehpur, the City of Victory. In 1585 Akbar left for a campaign in the Punjab and did not return to rule from it; by around 1610 the city was deserted. Water shortage is the usual explanation, though historians also point to the emperor's changing priorities.

    Did you know? The English traveller Ralph Fitch, who saw the court in the 1580s, judged both Agra and Fatehpur Sikri to be much larger than London.

26. 26 Galle Fort

    Sri Lanka · 2.5 km from Galle6.027° N 80.217° E

    

    Galle Fort covers a small rocky peninsula at the southwestern tip of Sri Lanka: a whole town of 52 hectares enclosed by ramparts of granite and coral, with the Indian Ocean on three sides. Within the walls, a grid of streets is lined with low gabled houses and verandahs, churches, mosques and old warehouses, and many streets still carry Dutch names. UNESCO listed the Old Town of Galle and its Fortifications in 1988 as a rare meeting of European architecture and South Asian traditions from the 16th to the 19th centuries.

    Did you know? The waters of Galle harbour hide more than 21 historic shipwreck sites, which led to a maritime archaeology centre opening inside the fort in 1997.

27. 27 Ani

    Turkey · 39 km from Gyumri40.508° N 43.573° E

    • UNESCO World Heritage

    

    Ani stands on a high, triangular plateau in eastern Anatolia, and the first thing to understand about it is the silence. Here, between deep river gorges, lay the capital of Bagratid Armenia from 961 to 1045 - a city that under King Gagik I may have held around 100,000 people, rivalling the great cities of its age. Its nickname, "the city of 1,001 churches", is a poetic exaggeration, but not by as much as it sounds: archaeologists have counted some fifty churches, more than thirty cave chapels and twenty smaller chapels. Today the grass plateau is empty, and the churches stand alone and far apart, the colour of rust and honey against a huge sky.

    Did you know? Trdat, the architect of Ani Cathedral, was also summoned to Constantinople to rebuild the dome of Hagia Sophia after an earthquake brought it down, returning in 993.

28. 28 Rohtas Fort

    Pakistan32.965° N 73.576° E

    • UNESCO World Heritage

    

    Rohtas Fort is a military machine rather than a palace, and that is what makes it exceptional. Sher Shah Suri, the Afghan ruler who had driven the Mughal emperor Humayun into exile, founded it around 1541 on a hill above the Kahan river in the Tilla Jogian range. It was meant to block Humayun's return and to subdue the Gakhars, a local tribe loyal to the Mughals. Construction was supervised by Todar Mal, his finance minister; the Gakhars at first refused to work for him, and only sharply raised wages brought labourers to the site. Sher Shah died in 1545, before it was finished.

    Did you know? The fort takes its name from Rohtas in Bihar, a hill fortress Sher Shah Suri had captured in 1539, just before building this one.

29. 29 Baltit Fort

    Pakistan36.326° N 74.670° E

    

    Baltit Fort rises above Karimabad in the Hunza Valley like a wooden-and-stone ship moored on a ridge, its whitewashed upper storeys and carved timber balconies set against the great snow walls of the Karakoram. Ultar Peak towers behind it, and the view across the valley reaches toward Spantik and other summits of one of the highest ranges on earth. Few historic buildings anywhere sit in a landscape of such scale.

    Did you know? The walls are reinforced with timber cribbage, known locally as kator, which has carried the fort through many earthquakes.

30. 30 Derawar Fort

    Pakistan28.767° N 71.334° E

    

    In the flat, sandy expanse of the Cholistan Desert in southern Punjab, the walls of Derawar Fort rise straight out of the plain, ringed by forty massive round bastions that can be seen from miles away. The square fortress is built of fired clay brick, its walls running for about 1.5 kilometres around the perimeter and standing up to thirty metres high, with ten bastions on each side. Many of the bastions are worked with patterns cut into the brick. Of the chain of desert forts that once guarded this region, Derawar is the best preserved.

    Did you know? The fortress covers about 35 acres, and each of its forty bastions rises around 30 metres above the desert floor.
