The Stadtgarten (City Garden) of Freiburg is a 2.6 ha park within the Neuburg district. It has an old tree grove and a large rose garden, and lies between the Leopoldring, Jackob Burckhardt, Ludwig and Mozart streets near Freiburg's city centre. It is connected to Karlsplatz via the Karlssteg footbridge, which is made from pre-stressed concrete. Since 2008 the Schlossberg Tram, an inclined elevator, leads up to Schlossberg. It replaced the Cable Car built in 1968.
