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. In 2009–10,
Canterbury City Council considered closing the museum, now called the Westgate Towers Museum, which proved to be a controversial option. An additional year's funding was made available to give time to examine alternative operating models, and in 2011 the museum was reopened by Charles Lambie, the chairman of the trustees of
Canterbury Archaeological Trust, who intended to build an extension to the building focusing on the penal history of Westgate. Lambie died in 2012, having invested £1 million in the project, causing the closure of the museum and generating fresh questions about the building's future. In 2014, the council agreed to assign the lease to the One Pound Lane company, who stated that they intended to reopen the existing museum and develop a restaurant and bar in the premises. The Westgate reopened to the public on 3 August 2015. In the 21st century, Westgate is the largest surviving city gate in England. ==Architecture==
