The North Town Wall runs from the Bargate to the Polymond Tower, including the two half-round interval towers, was built in the late 13th century. It replaced an earlier earthen rampart and timber palisade. The towers were originally equipped with arrow-slits most of which were converted to keyhole gunports in the late 14th century. A deep and wide moat ran along the front of the wall. This wall, at the moment (late 2019) , is not available to be accessed or seen due to works around the wall but hopefully once the building has been done around it it will be open to be viewed. The photos I have uploaded, front and rear views, is a true representation of the wall and were taken before work commenced around it. Some of the photos can also be seen on the Historic England website.
