Description

The Old Gaol is a gaol, largely rebuilt in 1796 and enlarged in 1816. It was later converted into flats in the late 20th century. The building is constructed of flint with gault brick dressings, and has a roof of black-glazed pantiles. The south-east gable wall was rebuilt in the 20th century using yellow brick. It is three storeys high and has four bays. All windows are located under segmental arches. There are two heavy plank doors set in round-headed recesses, flanked by an 8/8 unhorned sash window to the right and a blind window to the left. A further 8/8 sash window is located to the right of the right-hand door. The first floor is lit through four 4/4 sash windows. Above the doors are panels depicting carved shackles, and a plaque reads: ‘This Gaol was enlarged in the year 1816’. Four barred cell windows are present on the second floor. A dentil eaves cornice sits below a gabled roof. Internal gable-end stacks and a central ridge stack are visible. The north-west return has two 2-light casements on each floor, with shouldered lights. The interior of the building was not inspected.

Local climate

The Old Gaol sits in a drier-than-average part of the UK, with an average of 710 mm of rain a year. This makes it drier than 88% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 99% of listed buildings.

It experiences an average of 31 freeze-thaw cycles a year, fewer than 62% of listed buildings. Of these, 16 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
