The Westgate is a medieval gatehouse in Canterbury, Kent, England. This 60-foot (18 m) 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.

Canterbury is a city and UNESCO World Heritage Site, in the county of Kent, England; it was a county borough until 1974. It lies on the River Stour. The city has a mild oceanic climate.
