The Hexenturm, once a grim prison, remains from the time when Gelnhausen was the center of a witch hunt in the late 16th century. Dozens of women were either burned at the stake or bound hand and foot and then thrown into the Kinzig River. Suspects were held in the Hexenturm of the town battlements. Today it houses a bloodcurdling collection of medieval torture instruments. The tower is being renovated until sometime in 2014, so until then visitors who wish to venture inside are required to join a tour, which are offered in German on Sunday afternoon from May through October. English-language tours for groups of up to 30 people can be booked in advance for €52.
