Not all medieval castles had torture chambers. While some castles included spaces for torture as part of their dungeons or prison areas, many served primarily as fortifications and residences without such facilities. The presence of torture chambers depended on the castle's purpose, the lord's practices, and the legal customs of the region. Overall, torture was not a universal feature of medieval castles.
