Canterbury prison is not discussed by Pitt, however, records do survive that account for its use as a debtors’ prison and a set of papers is still extant that includes a debtor’s correspondence for the period 1675 to 1678. Neild does discuss the debtors’ prison from an early nineteenth century perspective, noting that the gaol was in the City’s West gate. It consisted of a day room and two rooms that were in the two towers of the gate, which the debtors slept in, “with only mats to lie on”.
