The Roundhouse, Warminster, Wiltshire
This building was once the town lockup. It was built in the 17th/18th century. They were used for locking up petty criminals, people who were drunk or people waiting to go to court. They were often built as part of a complex including the village pound, stocks and pillory. They date back to around the 1560s. Generally the lockup was used by the parish constable who had the unpaid job of keeping law and order in his own parish.
