Letzigrund

Letzigrund is a stadium in Zürich, Switzerland, the home of the football clubs FC Zürich and Grasshopper Club Zürich, as well as the athletics club LC Zürich. The original stadium was constructed by members of FC Zürich in 1925. Grasshopper Club has been using it as their home stadium since 2007, shortly after construction of the new stadium was completed.

The annual track and field meet Weltklasse Zürich, part of the Diamond League, has taken place at the Letzigrund since 1928, as have frequent open-air concerts. On the Letzigrund track on 21 June 1960, Armin Hary was the first human being to run the 100 metres in 10.0 seconds. LC Zürich was spun off of FC Zürich in 1934.
