Tuxford has a town lock-up: one of only three in Nottinghamshire. Built in 1823 it stands in Newcastle Street. It has two separate cells, one each for men and women, each with its own earth closet. Ventilation to each cell is via two circular holes, with iron bars on the front and back walls. In 1884 an extension was added to the back of the lock-up to house Tuxford's fire engine. Early maps show that also behind the lock-up was the town pinfold, which remained in use until the 1920s.
