The Westgate is a medieval gatehouse in Canterbury, Kent, England. This high western gate of the city wall is the largest surviving city gate in England. Built of Kentish ragstone around 1379, it is the last survivor of Canterbury's seven medieval gates, still well-preserved and one of the city's most distinctive landmarks. The road still passes between its drum towers. This scheduled monument and Grade I listed building houses the West Gate Towers Museum as well as a series of historically themed escape rooms. History 4th–18th centuries Canterbury was walled by the Romans around 300 AD. This has been consistently the most important of the city's gates as it is the London Road entrance and the main entrance from most of Kent. The present towers are a medieval replacement of the Roman west gate, rebuilt around 1380. There was a gate here at the time of the Norman conquest, which is thought to have been Roman. From late Anglo-Saxon times it had the Church of the Holy Cross on top, but both church and gate were dismantled in 1379, and the gate was rebuilt by Archbishop Simon Sudbury before he died in the Peasants' Revolt of 1381. It has been suggested that it was built primarily as an entrance for pilgrims visiting the shrine of St Thomas Becket at the cathedral. However the rebuild as a defensive status symbol was paid for partly by Sudbury and partly by taxation for military protection against expected raids by the French. In 1453 Henry VI permitted the Mayor and Commonality to keep a jail at the Westgate, so the building was Canterbury's prison from the 15th to the 19th century, while Canterbury Castle was the county jail. In January 1648, after the Christmas Day riot, Parliamentarians burnt down all the wooden doors of the city's gates. They were all replaced in 1660, but these replacements were removed at the end of the eighteenth century. They were similar to the surviving wooden Christ Church gates at the cathedral. After repairs to the Westgate and jail in 1667, a pound was built on the north side for the hail; this is now gone, but Pound Lane remains. The guard rooms, heavily wood-lined in the eighteenth century, became cells for both debtors and criminals, and the room over the arch became the condemned cell with the portcullis now laid on top. Until 1775 there was a
