18th–19th centuries
The castle rapidly deteriorated after the slighting and the remaining walls and bastions were taken down in 1785, leaving only the gatehouse and the earth motte.
The gatehouse remained in use as the county gaol into the 19th century, being run, like other similar prisons, as a private business – the keeper of the castle gaol was paid £200 a year by the county in 1807 (equivalent to £ in ).

This came to an end when a new county prison was built in the grounds of the castle's former bailey. The new prison was built by G. Byfield between 1807 and 1811 with an innovative octagonal structure, influenced by the designs of the prison reformer
