The Marienberg Fortress is situated only a stone's throw from the city centre on the left bank of the river Main. It is surrounded by vines and looks down to the old university town with its cupolas, towers and bridges. The Marienberg Fortress belongs to the most impressive monuments due to its rich historical past and its mighty appearance. The history of the castle can be followed throughout 3 millenniums.
A lovely walkway leads up to the Marienberg Fortress from St. Burkard. And the castle can be accessed on foot via the Tellsteige as well as via the terrain of the 1990 horticultural show.
