Aussichtsturm Schlossberg

The Schlossbergturm or Castle Hill Tower is a 35 m high observation tower on Castle Hill Schlossberg on the edge of the historic Altstadt of Freiburg im Breisgau.

It has 153 steps, its top is located 463 m above sea level and thus 185 m above the average altitude of the city (278 m).

The tower's twisted design includes six tree trunks (Douglas-firs from the municipal forest of Freiburg) around a staircase made of steel.

It has three platforms and the top is reached by a small spiral staircase.

The tower is built on the grounds of the Fort de l'Aigle von Auban, also known locally as "Salzbüchsle", which are a continuation of the Black Forest into the city of Freiburg.
