Rochester Castle [SEP] Henry III
John died in 1216 and was succeeded by his nine-year-old son, Henry, with the support of the barons. With no prospect of becoming King of England, Louis returned to France. Rochester Castle was returned to royal control in 1217. Given the damage incurred during John's siege, the castle was in dire need of repairs. Between 1217 and 1237 around £680 were spent on repairs, of which £530 were taken up by work on the keep. In 1225 and 1226 the town walls were enhanced by the addition of a ditch at the cost of £300. The new ditch enclosed Boley Hill, possibly to deny the position to future aggressors who might attack the castle.
