Hexenturm

The Hexenturm, or Witches' Tower, is one of the few remaining physical remnants of Heidelberg's medieval city fortifications. Situated near the Neckar river and the historic Marstall courtyard, this robust stone structure offers a glimpse into the city's defensive past. Originally built as part of the defensive wall, it later served as a prison, earning its ominous name during early modern witch trials, though its actual role in these events is often debated. Today, the tower stands as a silent sentinel among the bustling university buildings. Visitors walking through the historic old town can easily spot its striking cylindrical architecture, which contrasts beautifully with the surrounding baroque and modern structures. While the interior is generally not open to the public, the exterior serves as a fascinating photo opportunity and a tangible connection to Heidelberg's medieval history.
