1911 Encyclopædia Britannica/Trollhättan
TROLLHÄTTAN, a town of Sweden in the district (län) of
Elfsborg, 45 m. by rail N. by E. of Gothenburg. Pop. 6000.
It lies on the left (east) bank of the Göta at the point where that
river descends 108 ft. in the course of nearly a mile by the famous
falls of Trollhättan (six in number) and several rapids. The
scenic setting of the falls is not striking, but the great volume
of water, nearly 18,000 cub. ft. per second, renders them most
imposing. The narrowed river here surrounds several islands,
on either side of one of which (Toppö) are the first falls of the
series, Toppö and Tjuf. These are 42 ft. in height. The water-power
is used in rolling-mills, a cellulose factory and other works. Several “giant's caldrons” are seen in the exposed bed of a
former channel. Below the falls are valuable salmon fisheries.
To the east of the river the Berg canal, part of the Göta canal
system, ascends in a series of eleven new locks (Akersvass)
completed in 1844. An old series of locks (1800) is in use for
small vessels. There are also ruins of an abortive attempt
made to lock the falls in 1755. (See Goöta.)
