Not to be confused with nearby Tunbridge Wells, Tonbridge is home to Tonbridge Castle, an imposing Norman motte and bailey fortress protected by an massive gatehouse. The castle may be the best example in England of the motte and bailey style so favoured by the Normans. There is more to Tonbridge than the castle, though. The parish church of St Peter & St Paul is a 12th century building with a 14th century tower.
Tonbridge was granted a market charter in 1259, and there are quite a few buildings dating from the medieval periods to be seen about the town. Four miles distant is the lovely Elizabethan manor of Penshurst Place, while the moated manor house of Ightham Mote is only 5 miles distant.
