Trollhätte Canal During the 17th century, work on a system of locks began and the first lock was completed around 1607 at Lilla Edet. During the 18th century several unsuccessful attempts were made to complete the locks. In 1718 a contract was signed by the government and Christopher Polhem (1661–1751) for construction of a canal between Kattegatt and Lake Vänern and from Vättern to the Baltic Sea. Trollhätte Canal first begun construction in 1718. In 1800, Baltzar von Platen (1766–1829) completed the locks. Larger locks were later built under Nils Ericson (1802–1870). The further construction of the Göta Canal enabled larger boats to pass through Trollhätte Canal. Trollhättan Church Trollhättan Church (Trollhättans Kyrka) belongs to the Trollhättan congregation in the Diocese of Skara. Between 1860 and 1862, the New Trollhätte Canal Company (Nya Trollhätte Kanalbolag) built Trollhättan church. It was inauguration in 1862 and was handed over to the congregation as a gift. The church is erected in a neo-Gothic style after drawings by architect Adolf W. Edelsvärd (1824–1919). It consists of a longhouse with a north–south orientation. To the south is the tower with main entrance and to the north there is a polygonal cairn. It is located on a cliff in the Göta River in the middle of the canal system. At the expense of the canal company, a sacristy was built in the north-west in 1896–1897 with a rise to the pulpit, and the same year came glass paintings designed by Folke Zettervall (1862–1955). The window paintings in the choir, which was installed in 1962, are done by artist Ralph Bergholtz (1908-1988). The church was restored in 1983–84 with Jerk Alton as architect.
