History

Uto Kulm hosted a Celtic oppidum and later the medieval Uetliburg castle; the summit served as a watch post. By 1815, an inn opened at the former Hochwacht, launching Uetliberg’s excursion era.

The mountain railway opened in 1875, was electrified in 1923, and in 1990 was extended to today’s subsurface Zürich HB SZU terminus. The first iron lookout was built in 1894; the current steel tower dates to 1990 with a deck at 30 m; the 186.7-m TV tower also rose in 1990. The 1:1 billion Planet Trail has become a popular family ridge hike.
