What former Roman fort in Manchester, England, had material taken from it to build a medieval bridge also in Manchester?
Mamucium Mamucium, also known as Mancunium, is a former Roman fort in the Castlefield area of Manchester in North West England. The castra, which was founded c. AD 79 within the Roman province of Britannia, was garrisoned by a cohort of Roman Auxiliaries near two major Roman roads running through the area. Several sizeable civilian settlements (or "vicus") containing soldiers' families, merchants and industry developed outside the fort. The area is a protected Scheduled Ancient Monument.
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.
