What former Roman fort in Manchester, England, had material taken from it to build a medieval bridge also in Manchester?
Hanging Bridge Hanging Bridge is a medieval bridge spanning the Hanging Ditch, which connected the rivers Irk and Irwell in Manchester, England. The first reference to the bridge was in 1343, when it was called Hengand Brigge, but the present structure was built in 1421, replacing an earlier bridge. Material taken from Manchester's Roman fort may have been used in its construction. It has been speculated that the Hanging Ditch may be of Roman origin, part of a defensive circuit between the rivers Irk and Irwell.
