1. 01 Széchenyi Chain Bridge

   Hungary · 2.9 km from Budapest47.499° N 19.044° E

   

   Before 1849 Buda and Pest faced each other across the Danube with no permanent crossing. The Chain Bridge changed that. Count István Széchenyi championed the project, the English engineer William Tierney Clark designed it in 1839, and the Scottish engineer Adam Clark — no relation — supervised the work on site; the ironwork was made in Britain and shipped out in sections. When it opened in 1849, in the aftermath of the revolution of 1848, its 202 m central span was among the longest in the world, and it was the first permanent bridge across the Danube anywhere in Hungary.

   Did you know? In 1849 Austrian troops tried to blow up the new bridge; Adam Clark had flooded the chain chambers, and the charge left on the deck did little damage.

2. 02 Göltzsch Viaduct

   Göltzschtalbrücke

   Germany · 30.2 km from Gera50.623° N 12.246° E

   

   The Göltzsch Viaduct is a bridge built almost entirely out of small clay bricks — 26,021,000 of them, laid by hand between 1846 and 1851 — because the valley it crosses happened to sit on abundant loam deposits, and hauling in cut stone would have been slower and far more expensive than firing bricks on-site. That local-materials logic produced something that briefly held the record for the tallest railway bridge on Earth, and still holds the record, unchallenged, for the largest brick-built bridge in the world: 574 metres long, 78 metres high, narrowing from 23 metres wide at its base to just 9 metres at the top, carried across four stacked tiers of 98 arched vaults. Granite was reserved only for the structural points under the greatest stress; everything else the eye actually sees is brick.

   Did you know? An 1845 design competition drew 81 entries, but none could prove it would carry trains and none was built; one even proposed a prison inside the bridge.

3. 03 Corinth Canal

   Διώρυγα της Κορίνθου

   Greece37.927° N 22.995° E

   

   Emperor Nero personally struck the first blow with a golden pick in 67 AD, then put 6,000 Jewish prisoners of war to work digging trenches forty to fifty metres wide from both coasts at once, plus a separate crew boring test shafts down the ridge to check the rock. In roughly ten weeks they cut about 700 metres of the eventual channel — a tenth of the total distance — before Nero was declared an enemy of the state and killed. Work stopped, and nobody with both the money and the nerve tried again for eighteen centuries.

   Did you know? Instead of digging, the ancient Corinthians built the Diolkos, a paved stone trackway on which whole ships were hauled overland across the isthmus.

4. 04 Forth Bridge

   United Kingdom · 11.9 km from Edinburgh55.998° N 3.388° W

   • UNESCO World Heritage

   

   When the Tay Bridge blew down in 1879 with a train on it, work stopped on its designer's planned suspension bridge over the Firth of Forth. The engineers who replaced him, John Fowler and Benjamin Baker, set out to build something that could never be accused of flimsiness. The result, opened in March 1890, is the Forth Bridge: a railway viaduct 2.5 km long whose three great cantilever towers, each 110 metres high on granite piers, carry the double track 46 metres above high water. Its two main spans of about 520 metres were the longest in the world until 1919 and are still the second-longest of any cantilever bridge.

   Did you know? The Prince of Wales, later Edward VII, opened the bridge on 4 March 1890 by driving home a final rivet that was gold-plated and inscribed.

5. 05 Gornergrat Railway

   Gornergratbahn

   Switzerland · 38.8 km from Sion46.024° N 7.750° E

   

   The Gornergrat Railway climbs from the resort village of Zermatt, at about 1,604 metres, to a station at 3,089 metres on the Gornergrat ridge, facing one of the grandest mountain panoramas in the Alps. Opened on 20 August 1898, it was the first electric rack railway in Switzerland and the highest railway in Europe until the Jungfrau line opened in 1912; it remains the highest open-air line on the continent. Its trains are still powered by three-phase current, which is why each carries two pantographs under a pair of overhead wires, a system used on only a handful of lines in the world.

   Did you know? Work on the line began in 1896, only five years after the Visp–Zermatt railway first connected Zermatt to the Rhône valley.

6. 06 Mount Washington Cog Railway

   United States44.274° N 71.332° W

   

   The Mount Washington Cog Railway was the world's first mountain-climbing rack railway, and it still hauls passengers up the highest peak in the northeastern United States. Its founder, Sylvester Marsh, conceived the idea while climbing the mountain in 1852; paying passengers first rode in August 1868, and the track reached the 6,288 ft summit on 3 July 1869. The line is about three miles long and rises some 3,600 ft from its base station, and carries passengers from forest to the treeless summit.

   Did you know? The line is nicknamed the Railway to the Moon, after a legislator joked that Sylvester Marsh might as well be granted a charter to the moon.

7. 07 Big Hole

   South Africa · 1.4 km from Kimberley28.739° S 24.759° E

   

   The Big Hole in Kimberley is what remains of one of the great rushes of the nineteenth century. In 1871 diamonds were found on a small hill, Colesberg Kopje, on the farm of the De Beer brothers, and within weeks the hill was carved into hundreds of claims. The camp of diggers, called New Rush, grew to around 50,000 people and was renamed Kimberley in 1873 after the British Colonial Secretary. Diggers worked by hand with picks and shovels, and the hill turned into a pit.

   Did you know? Diamonds on Colesberg Kopje were found in 1871 by Esau Damoense, cook to Fleetwood Rawstorne's Red Cap Party, who had reportedly been sent there as a punishment.

8. 08 Jungfrau Railway

   Jungfraubahn

   Switzerland46.585° N 7.961° E

   

   The Jungfrau Railway climbs from Kleine Scheidegg, at 2,061 m, to the Jungfraujoch, at 3,454 m — the highest railway station in Europe. Its 9 km of metre-gauge rack track are mostly hidden: about four-fifths of the line runs inside a tunnel bored through the Eiger and the Mönch, where the snow and storms of the high Alps cannot reach it. Only the first stretch, up to Eigergletscher station, is in the open, and even that is the second-highest open-air railway line in Switzerland.

   Did you know? To prove the altitude was safe, in 1894 seven test subjects aged 10 to 70 were carried by porters to a 3,750-metre plateau on the Breithorn.

9. 09 Tower Bridge

   United Kingdom · 3 km from London51.506° N 0.075° W

   

   Tower Bridge was the answer to a very Victorian problem: how to join the fast-growing East End to the south bank without cutting off the ships that still unloaded in the Pool of London, between London Bridge and the Tower. A conventional fixed bridge at street level would have blocked their masts. After more than fifty designs had been rejected, the City chose a bascule bridge, and Parliament authorised it in 1885 on the condition, among others, that it should harmonise with the Tower of London next door. The architect was the City Architect, Horace Jones, and the engineer John Wolfe Barry. Construction began in 1886 and took eight years; the bridge was opened by the Prince and Princess of Wales on 30 June 1894.

   Did you know? In 1952 a double-decker bus was caught on the bridge as it began to open, and the driver accelerated across the widening gap, earning a ten-pound bonus.

10. 10 Glenfinnan Viaduct

    United Kingdom · 20.6 km from Fort William56.876° N 5.432° W

    

    The Glenfinnan Viaduct carries the single-track West Highland Line in a long curve across the valley of the River Finnan at the head of Loch Shiel, and it is hard to imagine a railway placed more beautifully. Twenty-one semicircular arches, each spanning 15 metres, march across the glen at a height of about 30 metres on a sweeping curve, for a total length of 380 metres. Built between 1897 and 1901 by Robert McAlpine and Sons, it is the longest concrete railway bridge in Scotland. McAlpine, nicknamed Concrete Bob, chose mass concrete, with no steel reinforcement at all, because the local schist was so hard to work; his son Robert ran the job at 28.

    Did you know? In 1987 engineer Roland Paxton used a borescope camera to look inside the piers for the legendary entombed horse and found no trace of it.

11. 11 Garabit Viaduct

    Viaduc de Garabit

    France44.975° N 3.177° E

    

    The Garabit viaduct carries a single railway track across the gorge of the Truyère in the Cantal, high in the Massif Central. Its centre is one great parabolic arch of wrought iron, 165 m wide and 52 m high, painted red and set against green hillsides. The whole structure is 565 m long. When the trains first crossed it, the deck stood about 122 m above the river, and for a time it was the highest viaduct in the world. Its arch was the longest ever built until the Dom Luís I Bridge in Porto overtook it in 1886.

    Did you know? The ironwork of the viaduct is held together by 678,768 rivets.

12. 12 Pont Alexandre III

    Pont Alexandre-III

    France · 3 km from Paris48.864° N 2.314° E

    

    Paris has older bridges and longer ones, but none so openly theatrical. The Pont Alexandre III crosses the Seine in a single low steel arch between the Invalides on the left bank and the Grand Palais and Petit Palais on the right, and it was built as a piece of diplomacy in metal and gilt. Tsar Nicholas II laid the foundation stone in October 1896, a gesture sealing the new Franco-Russian alliance, and the bridge, named after his father, opened for the Exposition Universelle of 1900 together with the two exhibition palaces beside it.

    Did you know? The single steel arch spans 107.5 metres and is built from 15 ribs, each assembled from 32 cast-steel segments.

13. 13 Clifton Suspension Bridge

    United Kingdom · 3.1 km from Bristol51.455° N 2.628° W

    

    The Clifton Suspension Bridge hangs across the Avon Gorge at its narrowest point, 245 feet above the river at high water, joining Clifton, on the Bristol side, to Leigh Woods in North Somerset. The bridge, a single span of just over 700 feet between two stone towers, sits across it with the lightness of a drawn line. It is the emblem of Bristol, and it is also a monument to its first designer, Isambard Kingdom Brunel, who won the commission and did not live to see it finished.

    Did you know? In 2002 engineers found twelve vaulted chambers hidden inside the Leigh Woods abutment, some of them about 35 feet high.

14. 14 Darjeeling Himalayan Railway

    India · 37.1 km from Ilam27.045° N 88.267° E

    • UNESCO World Heritage

    

    The Darjeeling Himalayan Railway, often called the Toy Train, climbs about 88 km from New Jalpaiguri on the plains of West Bengal to the hill town of Darjeeling, rising from roughly 100 metres to about 2,200 metres above sea level on a track only two feet wide. Built between 1879 and 1881, it follows the course of the old Hill Cart Road, the route of the horse-drawn tongas it replaced, and above Kurseong it squeezes through a busy shopping street.

    Did you know? When it was inscribed in 1999, it became only the second railway on the World Heritage List, after Austria's Semmering Railway.

15. 15 Elbląg Canal

    Kanał Elbląski

    Poland · 19.2 km from Elbląg54.024° N 19.598° E

    

    On the Elbląg Canal in northern Poland, boats leave the water and travel overland. Along a stretch of about ten kilometres the route has to climb roughly a hundred metres, too much for ordinary locks, and so vessels are floated onto wheeled cradles and hauled up grassy slopes on rails, then lowered into the next reach of water. The spectacle of a passenger boat gliding across a meadow has made the canal one of the best-known works of 19th-century engineering in Europe.

    Did you know? Building the canal lowered several lakes along the route, with Lakes Sambród and Piniewo dropping by more than five metres.

16. 16 Chania Lighthouse

    Φάρος Χανίων

    Greece · 0.8 km from Chania35.519° N 24.017° E

    

    The lighthouse of Chania stands at the entrance to the old Venetian harbour, a stone masonry tower that closes the view along the waterfront of this Cretan port. It rises about 26 m above the bay, with a gallery and lantern at the top.

    Did you know? The tower rises in three stages, an octagonal base, a sixteen-sided middle and a round top, which gives it the look of a slender minaret.

17. 17 Heceta Head Light

    United States44.137° N 124.128° W

    

    Heceta Head Light stands on a forested headland above the Pacific on the central Oregon coast, its white tower set on a ledge some 205 feet above the surf. The headland is named after Bruno de Heceta, the Spanish navigator who explored this coast in the late eighteenth century. Construction began in 1892 with a crew of 56, and the light was first lit in 1894.

    Did you know? Its Fresnel lens contains 640 two-inch-thick prisms arranged in eight bull's-eye panels, made in Birmingham, England.

18. 18 Lindau Lighthouse

    Leuchtturm Lindau

    Germany · 6.9 km from Bregenz47.543° N 9.684° E

    

    Lindau's lighthouse stands at the end of the western breakwater of the harbour of Lindau island, facing the Bavarian Lion on the opposite mole, and the two together form one of the most photographed harbour entrances on Lake Constance. It is the only lighthouse in Bavaria and the southernmost in Germany. Because the lake itself lies high, its light also burns at the greatest altitude of any in the country, some 428 metres above sea level.

    Did you know? The white flash is switched on by radio signals sent from ships approaching the harbour, rather than shining unattended all night.

19. 19 Saint-Mathieu Lighthouse

    Phare de Saint-Mathieu

    France · 21.5 km from Brest48.330° N 4.771° W

    

    Few lighthouses stand in company as strange as Saint-Mathieu's. The white tower with its red crown rises straight out of the ruined nave of a Benedictine abbey on the Pointe Saint-Mathieu, the cliff-edged headland at the western tip of Brittany where the Iroise sea meets the approaches to Brest. Beside it are a naval signal station and a memorial to French sailors lost at sea, so that one short walk takes in eight centuries of the coast's relationship with the sea.

    Did you know? The light has a range of about 29 nautical miles, roughly 55 km, and flashes white once every 15 seconds.

20. 20 Zollverein Coal Mine Industrial Complex

    Zeche Zollverein

    Germany · 4.5 km from Essen51.486° N 7.044° E

    • UNESCO World Heritage

    

    Zollverein is often called the most beautiful coal mine in the world, and the phrase is less of a joke than it sounds. Its Shaft 12, opened in 1932 and designed by Fritz Schupp and Martin Kremmer, treated a colliery as a piece of modern architecture: plain cubic buildings of steel trusses and reinforced concrete, with a double-trestle winding tower over the shaft. That tower became the emblem of German heavy industry and later of the Ruhr's reinvention, and it is the image most people bring home from Essen.

    Did you know? The 7.2-tonne coal cube on display measures 1.6 m along each edge and is described as the largest single block of coal ever cut.

21. 21 La Corbière lighthouse

    Jersey49.180° N 2.250° W

    

    At the southwestern tip of Jersey, where the island ends in a jumble of granite reefs, a white tower stands on a rock that is an island twice a day. La Corbière lighthouse was completed in 1874 to the designs of the engineer Sir John Coode, and it holds a quiet place in engineering history as the first lighthouse in the British Isles to be built of concrete. The tower itself is only about 19 metres tall, but set on its rock the lantern sits some 36 metres above high spring tides, throwing a white light up to 18 nautical miles and a red light up to 16.

    Did you know? The name La Corbière means 'the place where crows gather', from the local word for crow, although gulls have long since taken over the rocks.

22. 22 Keage Incline

    Japan · 4.8 km from Kyoto35.008° N 135.791° E

    

    The Keage Incline is a railway for boats. Between 1891 and 1948 it carried cargo and passenger boats on flat wagons up and down a 36-metre drop at the western end of the Lake Biwa Canal, the great engineering project that brought water from Japan's largest lake over the hills into Kyoto. The canal itself was built between 1885 and 1890 under Tanabe Sakurō, a young graduate of the Imperial College of Engineering in Tokyo who had written his thesis on the scheme and was then hired as its chief engineer. Where the canal reached the steep slope above Nanzen-ji, boats could not continue by water, so they were winched along rails some 582 metres long between the Keage and Nanzen-ji docks.

    Did you know? In August 2025 the incline became one of five Lake Biwa Canal structures named National Treasures, the first modern civil-engineering works in Japan so honoured.
