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.
Liddel Strength Liddel Strength is an ancient monument near Carwinley, Cumbria, in northwest England. It consists of the earthwork remains of an Anglo-Norman border fortification (the seat of the barony of Liddel) destroyed by the Scots in 1346 (a wooden motte and bailey castle at the time of its destruction; possibly earlier a ringwork) and fragmentary remains of a pele tower subsequently built upon the site. It lies on a cliff on the south bank of the Liddel Water, overlooking the Liddel Water's confluence with the River Esk; the last high ground before the Esk reaches the Solway Plain. The Liddel Water (upstream of the confluence) and the Esk (downstream) form the modern Anglo-Scottish border; formerly they were the southern boundary of the Debatable Lands.
