The castle was held by the de Clare family, one of the most powerful baronial families in medieval England.
The motte rises approximately 24 meters above the original ground level, providing a defensive vantage point over the Medway valley.
In 1264, the castle was besieged by Simon de Montfort during the Second Barons' War, causing significant damage that prompted the construction of the stone gatehouse.
The gatehouse design includes a 'murder hole' in the ceiling of the gate passage, intended for dropping projectiles on invaders.
The castle site sits atop the town's original medieval earthworks, which were repurposed for modern garden paths.
The iron gate mechanism, including the portcullis, remains a centerpiece of the guided audio tour.
Tonbridge Castle is a 13th-century stone gatehouse that remains one of the best-preserved examples of its kind in England. The site features a Norman motte constructed shortly after the 1066 invasion, followed by the stone fortifications built by the de Clare family. Visitors access the castle via an audio tour that explores the gatehouse chambers and the historical function of the curtain wall. The site is situated on a man-made mound overlooking the River Medway. Archaeological evidence suggests the site served as a strategic administrative center throughout the medieval period. The current structure replaced an earlier wooden timber keep. The gatehouse retains its original portcullis grooves and medieval masonry details.

Wear comfortable, flat walking shoes to navigate the steep, uneven grass slope leading to the top of the motte.
Check the audio tour availability upon arrival, as it provides the primary historical context for the gatehouse interior.
Allow time to walk the perimeter path at the base of the motte to view the surrounding defensive earthworks.
Do not attempt to climb the steep motte during or after rainfall, as the grass becomes extremely slippery.
The interior of the gatehouse is occasionally closed for private events or during winter months; checking the official website for seasonal status is recommended.
