One of the oldest and best-preserved Jewish ritual baths in Europe, Speyer's Mikwe dates to around 1128. You descend a steep stone staircase about ten metres underground to reach the bath chamber, fed by groundwater. The Romanesque masonry is striking — clean lines, rounded arches, and a stillness that feels almost sacred.
The Mikwe sits in the courtyard of what was once the Jewish quarter, steps from the ruins of the medieval synagogue. Together they form part of the ShUM Sites, the Jewish heritage of Speyer, Worms, and Mainz, which received UNESCO World Heritage status in 2021. A small exhibition near the entrance explains the ritual significance of the bath and the history of the Jewish community in Speyer, which was one of the most important in medieval Europe.
