The Westgate is a medieval gatehouse in Canterbury, Kent, England. This 60-foot-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, and there is just enough room for a double-decker bus to pass beneath. This scheduled monument and Grade I listed building houses the hundred-year-old West Gate Towers Museum, which as of July 2011 was open every day from 10am to 4:30pm, although it is currently closed for legal reasons. Access to the museum and roof is via spiral staircases only.
