The guardian angel by the French-Swiss painter and sculptor Niki de St. Phalle in the large hall in Zurich's main station was a gift from the artist on the station’s 150th anniversary. The angel has been hovering high above the heads of the travellers since 1997 and watching over them day and night.
It’s just like Zurich to boast Switzerland’s only tram museum. The historic Depot Burgwies is home to the collection, up to twenty original cars, the eldest dating back to 1897. It also features an exhibit on the development and workings of the Zurich tram.
