Description

The Roundhouse at Maidstone Prison was built between 1809 and 1811 by Daniel Alexander. Originally, the lower floors served as the Keeper's House, while the top floor housed a chapel designed so that inmates could see the prison chaplain without seeing other prisoners. This circular building has four storeys and a basement, with the ground floor featuring rusticated stonework. It has a slate roof topped with a clock and a total of eight windows. The first and second floors have modified Venetian windows, while the third floor features three-light lunettes. There is a moulded eaves cornice and an additional cornice between the third and fourth floors, along with a stone stringcourse separating the ground and first floors. The ground floor includes three-light windows set in segmental arches with keystones, and the glazing bars are intact on the ground and first floors. The main entrance is located in a rusticated stone gabled porch with a slate roof, featuring a round-headed doorcase with stone voussoirs and a keystone, and one round-headed window on each side of the porch. There are steps leading to the street, and inside, there is a circular cast iron staircase. All the listed buildings at Maidstone Prison form a group.
