Great view of the castle from the bridge over the River Medway. A motte-and-bailey castle was built on this site after the Norman conquest as further defence. The castle as it looks to today was built in the 13th Century, and the mansion was added in the 18th Century. The council now use the mansion for offices, but the castle is worth a visit.
