Entering the Zinwegorinklaus is the only way to see inside the Schwabentor, which is only open from May to October as there is no heating in the building; It is like discovering a hidden treasure! A spiral staircase of 50 steps leads to a small room within the historic confines of Schwabentor. The curiosity of visitors is awakened by the old stone walls of the former defense tower, the small windows and the old street lamps, as this place is an amazing experience not to be missed.
