In short: By our ranking, the most impressive city walls in Europe are Walls of Ávila (Spain), Walls of Dubrovnik (Croatia) and Conwy Town Walls (United Kingdom). The list covers 8 city walls in 7 countries. Croatia has the most, with 2. Last updated 13 October 2026.
For most of its history a European town was defined by its walls. They marked the line between the law of the city and the countryside outside, guarded the markets and the right to tax them, and were rebuilt and extended for centuries. Most were torn down in the nineteenth century to make room for boulevards and railways, which makes the towns that kept a complete ring all the more remarkable.
The Walls of Ávila, built of granite in the Romanesque period, encircle the old city with more than eighty towers and nine gates and are among the most complete medieval town walls in Europe. The Walls of Dubrovnik run unbroken around the old town above the Adriatic, anchored by the round Minčeta Tower. Conwy Town Walls in Wales were raised by Edward I together with his castle, and the Fortifications of Kotor climb in zigzags up the mountain behind the town to the fortress of St John.
The northern walls belong to the world of the Hanseatic merchants. The Walls of Tallinn still stand along much of their length with red-roofed towers, and the Visby City Wall on the island of Gotland is the best-preserved medieval town wall in Scandinavia. In Tuscany, Monteriggioni is a small hilltop village enclosed by a ring of towers that Dante compared to giants in his Inferno. The Walls of Ston on the Pelješac peninsula, built by the Republic of Ragusa to protect its salt pans, are among the longest fortification systems in Europe.

Muralla de Ávila
Spain40.657° N 4.707° W

The figures are impressive. 5 km; they are on average 3 metres thick and 12 metres high, punctuated by more than eighty semicircular towers, the "cubos", and around 2,500 merlons. There are nine gates, each once watched over by a noble palace whose family was responsible for its defence. The two strongest face east, over the flat ground where an attacker would come: the Puerta de San Vicente and the Puerta del Alcázar, each flanked by twin towers about 20 metres high and joined by an arch. The Alcázar gate even carries a bridge between its towers, and it was here that the "Farce of Ávila" took place, when rebellious nobles deposed King Henry IV of Castile in effigy.
Did you know? Peasants of the surrounding countryside bore some 80 per cent of the city's infrastructure costs, including the upkeep of the walls, known as the reparo de los muros.
Dubrovačke gradske zidine
Croatia · 2.7 km from Dubrovnik42.640° N 18.108° E

The ring was outlined in the fourteenth century but kept evolving from the thirteenth to the seventeenth, as the merchant republic of Ragusa adapted it to each new threat. The republic hired some of the best builders of its age. Michelozzo di Bartolomeo, the Florentine who worked for the Medici, reshaped the defences in the early 1460s; Juraj Dalmatinac of Šibenik followed him; and the local master Paskoje Miličević spent decades refining the system. Their work shows most clearly in the round Minčeta Tower of 1463, the high crown of the landward walls, and in the two-storey casemate of Fort Bokar, which guards the western approach just above the sea.
Did you know? The walls of Lovrijenac facing the enemy are almost 12 metres thick, while the wall turned towards the city is no more than 60 centimetres.

Many details reward a close look. The towers are open at the back, spanned originally by removable timber bridges, so that any stretch of wall could be cut off if an enemy got onto it. The Upper Gate keeps a rare surviving barbican. Along the southern wall, a unique row of twelve medieval latrines, built for the royal staff, projects from the parapet — a rare glimpse of everyday life in the Edwardian town. A hall built into the walls for Edward, known as Llywelyn's Hall, did not stay: in 1316 it was taken down and moved to Caernarfon Castle.
Did you know? The accounts never separated the walls from the castle: together the two projects cost around £15,000, an enormous sum for the late 13th century.
Montenegro42.425° N 18.771° E

The mountain top was fortified in Illyrian times and rebuilt under the Byzantine emperor Justinian in the sixth century, but most of what stands today is Venetian. Kotor came under Venice in 1420, and over the following centuries the walls were rebuilt for gunpowder warfare and withstood two Ottoman sieges. Along the waterfront you pass the Kampana tower and citadel of the thirteenth and fourteenth centuries, the Sea Gate of 1555, the River Gate of 1540 beside the Bembo Bastion (now an open-air theatre), and the Gurdić Gate with its bastion of 1470.
Did you know? The bombardment of the French garrison opened on Christmas Day 1813; the British lost only one seaman killed in the whole siege.

The wall grew with the weapons it had to face. Early sections were about 6.5 metres high and more than 2 metres thick; in the fifteenth century they were raised to 11–16 metres, and the towers became heavier as artillery arrived. The most imposing is Kiek in de Kök, a powerful cannon tower built in 1475–1483. Near the harbour stands Fat Margaret, a squat artillery tower of 1510–1531, 22 metres high, which now houses a maritime museum. The Maiden Tower, a guard tower of 1360, and the tall Nunnatorn, which incorporates older convent walls, give the circuit its fairy-tale profile.
Did you know? That first wall was a patchwork of 60 to 70 sections of differing heights, apparently built by different masters, with a wooden walkway on top.
Visby ringmur
Sweden · 0.8 km from Visby57.640° N 18.294° E

The oldest piece is Kruttornet, the Gunpowder Tower, built around 1160 to guard the harbour and the oldest surviving secular building in the Nordic countries. The landward wall followed from the 1270s and 1280s, and gates such as Österport, Norderport and Snäckgärdsporten were built around 1290; in the 1350s the wall was raised by three or four metres. Its history is written in its stones. In 1361 King Valdemar IV of Denmark took Gotland, and local tradition holds that he had part of the wall pulled down so he could enter as a conqueror; the fifteenth-century Jungfrutornet, the Maiden's Tower, has its own legend tied to that invasion.
Did you know? The Gunpowder Tower was raised in 1160–61 in connection with a trade agreement with the Duke of Saxony, and once had a twin across the harbour.
Italy · 12.1 km from Siena43.367° N 11.218° E

The castle was founded by the Republic of Siena, which began building it in 1214 on a hill of the Montagnola Senese, about 274 metres above sea level. It was a frontier fortress, raised to guard the routes through the Elsa and Staggia valleys against Florence, Siena's great rival. The walls, about 570 metres around and some two metres thick, follow the curve of the hilltop in a roughly circular plan and are punctuated at intervals by square towers. Two gates open in the circuit: the Porta Fiorentina, facing north towards Florence, and the Porta Romana, facing south towards Rome, joined by the main street that crosses the village.
Did you know? Many of today's tower tops are not medieval: they were rebuilt in the 1920s so the silhouette Dante described could again be seen from the Via Cassia.
Stonske zidine
Croatia · 37.8 km from Dubrovnik42.838° N 17.697° E

Ragusa bought Ston and Pelješac from the Serbian Empire in 1333 and started work on the defences in 1358. The system was designed as a whole: a wall across the isthmus linking two planned towns, Ston on one side and Mali Ston on the other, each laid out on a regular grid and each guarded by its own fortress — the Veliki Kaštio in Ston and the Koruna in Mali Ston — with a further fort on Podzvizd hill at 224 metres. Some of the best-known builders of the Adriatic worked on it, including Michelozzo and Juraj Dalmatinac (Giorgio da Sebenico). By the 15th century the walls carried around 40 towers and five fortresses; the Field Gate in Ston bears a Latin inscription dated 1506.
Did you know? The main stretch across the isthmus, the Great Wall, runs for about 1,200 metres on its own.
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
