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.
Portland Castle Portland Castle is an artillery fort constructed by Henry VIII on the Isle of Portland, Dorset, between 1539 and 1541. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Portland Roads anchorage. The fan-shaped castle was built from Portland stone, with a curved central tower and a gun battery, flanked by two angular wings. Shortly after its construction it was armed with eleven artillery pieces, intended for use against enemy shipping, operating in partnership with its sister castle of Sandsfoot on the other side of the anchorage. During the English Civil War, Portland was taken by the Royalist supporters of King Charles I, and then survived two sieges before finally surrendering to Parliament in 1646.
