The Witches' Tower in Słupsk was built at the beginning of the 15th century as part of the city's defensive wall. Since 1976, its restored interior houses an art gallery. An exhibition space is organized on three levels, where exhibitions of paintings, sculptures, photographs, drawings, graphics and spatial installations are presented.
In the 17th century, the defensive tower was transformed into a prison where women accused of witchcraft were detained and tortured. Most likely, 18 women were executed here. The first witch trial took place in 1651, and the last execution was carried out in 1714.
In the following centuries, the interior of the tower was transformed into apartments, stables and again a prison. During the Second World War, the building was significantly damaged. It was rebuilt in the 1970s.
