The Hexenturm in Fulda is a 14 meter high tower of the medieval city fortification. The tower, built in the 12th century, was part of the inner city wall and part of the north gate. The gate and tower separated the city from the monastery district. The Witch Tower is the best preserved tower of the medieval city fortifications of Fulda. The tower, which was originally the watchtower of the city wall, was later used as a women’s prison. According to original documents from 1603, however, the victims of the witch hunt were demonstrably not held in this tower, but in the Fulda City Palace. In the vernacular, the name Hexenturm did not appear until the end of the 19th century. Files from the Fulda City Archives show that the tower was called "Turm am Frauentörlein" in 1808, which is also documented in 1845 by a contemporary drawing. On the tower there is a sign for the memorial to the 270 victims of the witch hunt in Fulda, which was built in November 2008 in the Old Cathedral Parish Cemetery. The birthplace of the inventor of the Braun tube, Ferdinand Braun, is in the immediate vicinity of the tower on Kanalstrasse in Fulda. The witch tower is open to the public. It forms the station No. 11 of the touristic audio guide tour through Fulda.
