16th century extension behind Walmgate Bar

Although Walmgate is the only bar to retain its barbican, portcullis and inner doors, it has had a more torrid history than the other bars. It was burned by rebels in 1489 and battered by cannon during the siege of 1644. Until the late 19th century each of the 4 main bars had a barbican (an outer wall and gateway) just like the one that survives at Walmgate.
