The Stolper Tower is located in Stolpe an der Oder and is part of a former walled castle with ring wall and gatehouse. The popularly called Grützpott tower is with 18 m outside diameter probably the thickest keep in Germany. You can reach the tower on the tour Chorin – Brodowin – Pehlitz – Parstein – Stolzenhagen – Stolpe – Schwedt, where you can return the bike rented at the bike rental station Chorin and return home by train.
