The Greatest Engineering Wonders in Norway
8 places · updated 13 October 2026
In short: By our ranking, the greatest engineering wonders in Norway are Lærdal Tunnel, Flåm Line and Vemork. The list covers 8 engineering wonders. Last updated 13 October 2026.
Norway's engineering is a response to its landscape. Fjords cut the coast into peninsulas and islands, mountains rise straight from the sea, and heavy rain and snowmelt pour down steep valleys. That made travel hard and power plentiful: Norwegians built tunnels, bridges and mountain roads to tie the country together, and harnessed falling water so thoroughly that hydropower supplies almost all of the country's electricity.
The Lærdal Tunnel runs for 24.5 kilometres beneath the mountains of western Norway, with caverns lit in blue and yellow to break the long drive. Trollstigen climbs a steep valley wall in a series of hairpins beside a waterfall, and the Storseisundet Bridge on the Atlantic Ocean Road arcs so steeply that from some angles it seems to end in mid-air. The Flåm Line descends from the mountain plateau to the Aurlandsfjord on one of the steepest standard-gauge railways in the world.
The hydropower story is told at Rjukan in Telemark. Vemork was a pioneering power station and the site of the wartime sabotage of its heavy water plant, and Såheim Power Station, still in operation in the town below, is part of the same industrial landscape. On the Telemark Canal the Vrangfoss Locks lift boats past a waterfall in a flight of stone chambers, and the Loen Skylift climbs from the Nordfjord to the summit of Mount Hoven in one steep cable span.

01 Lærdal Tunnel
Norway60.972° N 7.368° E
W. Bulach · CC BY-SA 4.0 What makes it more than a feat of engineering is the way its designers thought about the people inside. A twenty-minute drive through unbroken rock is a strain, so the tunnel was divided into four sections by three great caverns, spaced about 6 km apart. In these caves the lighting changes: the white of the tunnel gives way to deep blue with yellow at the edges, meant to suggest the light of dawn.
Did you know? Each lane has a raised rumble strip along the centre line, designed to jolt drowsy drivers on the long, straight run.
02 Flåm Line
Norway60.863° N 7.115° E
W. Bulach · CC BY-SA 4.0 The trip is less a transfer than a descent through a sequence of landscapes. At the top, Myrdal sits among bare fells and snowfields, reachable only by rail. Below, the train edges along the steep walls of Flåmsdalen, with waterfalls falling from the cliffs on both sides and the valley floor opening up hundreds of metres beneath.
Did you know? When the line opened, trains took 65 minutes downhill and 80 minutes uphill; today the journey takes about 50 and 59 minutes.
03 Vemork
Norway59.872° N 8.494° E
Image by Moellenborg from Pixabay In 1934 a plant at Vemork began producing heavy water, a by-product of hydrogen production that no other factory in the world then made in quantity. During the German occupation of Norway it became one of the most important targets of the Second World War, because heavy water was seen as a route to an atomic bomb. A British glider raid in November 1942 ended in disaster, with the survivors executed.
Did you know? The only person the commandos met inside the plant was a Norwegian caretaker, and all ten men of the combined teams escaped afterwards.
04 Trollstigen
Norway62.457° N 7.673° E
Image by plutozoom from Pixabay The setting is as much the point as the engineering. Peaks well over 1,000 metres — among them Bispen, Kongen and Dronningen, the Bishop, the King and the Queen — crowd around the pass, and the Stigfossen waterfall drops down the mountainside right beside the bends, crossed by the road on a bridge. Early in the season the road runs between walls of old snow even when the valley below is green.
Did you know? The bridge that carries the road across the Stigfossen waterfall was built in 1934–1935 and is often drenched by spray when the river runs high.
05 Storseisundet Bridge
Norway · 31.2 km from Molde63.017° N 7.354° E
Image by Rob026 from Pixabay Storseisundet is a cantilever bridge 260 metres long, with a main span of 130 metres and 23 metres of clearance for boats beneath it. 3 kilometres between Kårvåg on the island of Averøya and Vevang on the mainland. The road took six years to build, from August 1983, and during that time the exposed site was hit by twelve severe European windstorms. The boundary between the municipalities of Averøy and Hustadvika runs beneath the bridge.
Did you know? The entire road, Storseisundet included, cost about 122 million Norwegian kroner, paid half by state grants, a quarter by job-creation funds and a quarter by tolls.
06 Såheim Power Station
Norway59.877° N 8.593° E
Jac Brun · Public domain The station was the second great step in harnessing the Måna river, which drops from the lake Møsvatn through the Vestfjord valley. 7 km long, begun in January 1912; construction of the station itself started in 1914, and it was formally put into service in January 1916.
Did you know? A small separate plant, known as Aggregat 12, was built about 85 metres inside the mountain above the main station.
07 Vrangfoss Locks
Norway · 25.3 km from Skien59.302° N 9.204° E
christophe Dayer from onex, Suisse · CC BY-SA 2.0 The flight was built between 1887 and 1892 as part of the Bandak–Norsjø Canal, the second and more ambitious phase of the system, and when it opened the canal was hailed as a kind of eighth wonder of Europe. The gates are still worked by hand, with lock-keepers pushing long poles to swing them open. A full passage through all five chambers takes about an hour.
Did you know? King Oscar II and Prince Eugen visited on 29 October 1893, and their signatures were also carved on stones by the uppermost chamber.
08 Loen Skylift
Norway61.880° N 6.837° E
Bingar1234 · CC BY-SA 4.0 5 kilometres of track rope between the stations. Each cabin carries up to 45 people and travels at up to seven metres per second. Queen Sonja of Norway opened it in May 2017, and it was the first aerial tramway to be built in Norway since the 1960s. It is owned by a local company whose shareholders include the Hotel Alexandra in Loen, the lift's manufacturer and the municipality of Stryn.
Did you know? Planners budgeted for 55,000 passengers in the first season, but about 92,000 people rode the lift by the end of 2017.
How this list is ranked
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.
Questions people ask
- What are the greatest engineering wonders in Norway?

- What happened at Vemork?
- During the Second World War the hydroelectric plant at Vemork produced heavy water that Nazi Germany sought for its nuclear research. In February 1943 Norwegian commandos sabotaged the plant in Operation Gunnerside.
- Why does Norway get so much electricity from hydropower?
- Steep mountains, abundant rain and snowmelt, and many lakes at high altitude give the country a great deal of falling water. Hydropower plants supply nearly all of Norway's electricity.
