market town in the English county of Kent, with a population of 40,356 in 2015. It is located on the River Medway, approximately 4 miles (6 km) north of Royal Tunbridge Wells, 12 miles (19 km) south west of Maidstone and 29 miles (47 km) south east of London. It belongs to the administrative borough of Tonbridge and Malling (population 120,805 in 2011).
Tonbridge stands on spur of higher land where the marshy River Medway could be more easily forded. Ancient trackways converged at this point. There is no record of any bridge before 1191. For much of its existence, the town remained to the north of the river, since the land to the south was subject to extensive seasonal flooding. One part of the town is called ‘Dryhill’. Richard Fitz Gilbert de Clare founded the Priory of St Mary Magdalene in 1124.
A castle was built here in the 11th century by Richard Fitz Gilbert, son of the murdered guardian of William the Conquerorin his infancy. Richard was responsible for governing England in William I’s many absences." />
