Her Majesty's Prison: Perimeter wall

Her Majesty's Prison perimeter wall was built between 1848 and 1849 by Thomas Smith. It is constructed of English bond red brick, with round corners in header bond and features ballnose brick coping. The walls are tall and approximately rectangular in shape, oriented on a north-south axis, with rounded corners and an entrance block along with wings at the southern end. There are round turrets topped with large rusticated stone domed caps.

This perimeter wall is part of the extension of Bedford Prison, which was originally built in 1801 to the designs of John Wing. The extension included the rebuilding of the perimeter walls and front entrance, along with the addition of flanking front wings by Thomas Smith, who served as the County Surveyor for Hertfordshire and Bedfordshire.
