Trollhättan, Västergötland, Exploring Sweden

Trollhättan, Västergötland – Exploring Sweden

Trollhättan is a city in the province of Västergötland and has historically been one of the industrial centers of Sweden. The most famous company from here is Saab Automobile, which once employed many of the city’s around 50.000 inhabitants. This is a city built along the canal and the hydroelectric power plant next to its center.

A Short History of Trollhättan

Trollhättan was earlier known as Stora Edet, meaning the large land passage between two waterways. Most likely the name is associated with the large rapids found here. For a long time, they prevented boats from passing along the river. A bit further downstream is the locality Lilla Edet, the small land passage. The current name, Trollhättan, comes from the belief that trolls lived in the rapids and that the visible stones were their caps.

The Canal

The history of the area is closely connected with the river Göta Älv. The river and its rapids were an obstacle that was discussed already in the 16th century. The first lock at the smaller rapids in Lilla Edet was completed in 1607, but it took until the year 1800 before the locks and canal were completed in Trollhättan. The canal was, however, a success and by many at the time claimed as the eighth wonder of the world. The canal then connected lake Vänern, the largest lake in Sweden, with the sea of Kattegat on Sweden’s western coast. With the opening of Göta Canal in 1832, Lake Vänern was now also connected with the eastern coast of Sweden.

Even though the population had grown and Trollhättan had become one of the largest urban areas in Sweden, it took until 1857 before it received its town charters.

Hydroelectric Power

The second large development in Trollhättan occurred in the early 20th century. This was when the Swedish state looked at the possibility to harvest the energy in the rapids. The construction of the first hydroelectric power plant started in 1907 and took three years to complete. The first power station was named Olidan and was joined by Hojum in 1942.

The power plant was initially run by the company Trollhätte Kanal- och Vattenverk, which was owned by the Swedish state. The company would be the foundation of Kungliga Vattenfallsstyrelsen in 1909, the state-owned power company that is today known as Vattenfall and operates in several European countries.


Industrialization would be the third event that really formed today’s Trollhättan. The company Nohab was established in 1847 and it produced turbines and eventually locomotives. Nohab closed down in 1986 but was prior to that able to start manufacturing airplane engines in 1930. This manufacturing would result in a new company, first named Svenska Flygmotor. The name changed to Volvo Aero Corporation and is today GKN Aerospace. An even more famous company was founded here in 1937.

Svenska Aeroplan AB, also known as SAAB, was established to secure the Swedish manufacturing of fighter airplanes. After the Second World War, Saab decided to start production of cars as a replacement for the expected decline in demand for airplanes. In 1946 the first prototype was completed and the production in Trollhättan started a few years later. Saab Automobile has since ceased to exist after years of trying to save the business when the 10-year ownership by General Motors came to an end in 2010. Saab was acquired by NEVS in 2012.

The Canal Locks at Gamle Dal

Since 1800 there have been three canals with locks built in Trollhättan, in 1800, 1844, and 1916. It is only the newest that is still in use, but they all still exist. The locks are locked in a park area known as Gamle Dal and during summers visitors can see the many leisure boats travel through the locks.
