Question: What former Roman fort in Manchester, England, had material taken from it to build a medieval bridge also in Manchester?
Context: Brougham Castle (pronounced ) is a medieval building about 2 mi south-east of Penrith, Cumbria, England.  The castle was founded by Robert de Vieuxpont in the early 13th century.  The site, near the confluence of the rivers Eamont and Lowther, had been chosen by the Romans for a Roman fort called Brocavum.  The castle is scheduled as an Ancient Monument, along with the fort, as "Brougham Roman fort and Brougham Castle". Castleshaw Roman fort was a castellum in the Roman province of Britannia.  Although there is no evidence to substantiate the claim, it has been suggested that Castleshaw Roman fort is the site of Rigodunum, a Brigantian settlement.  The remains of the fort are located on Castle Hill on the eastern side of Castleshaw Valley at the foot of Standedge but overlooking the valley.  The hill is on the edge of Castleshaw in Greater Manchester.  The fort was constructed in c. AD 79, but fell out of use at some time during the 90s.  It was replaced by a smaller fortlet, built in c. 105, around which a civilian settlement grew.  It may have served as a logistical and administrative centre, although it was abandoned in the 120s. Bowes Castle was a medieval castle in the village of Bowes in County Durham, England.  Built within the perimeter of the former Roman fort of Lavatrae, the early timber castle on the site was replaced by a more substantial stone structure between 1170 and 1174 on the orders of Henry II.  A planned village was built alongside the castle.  Bowes Castle withstood Scottish attack during the Great Revolt of 1173-74 but was successfully looted by rebels in 1322.  The castle went into decline and was largely dismantled after the English Civil War.  The ruins are now owned by English Heritage and run as a tourist attraction. 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. Barnstaple Long Bridge is a medieval bridge linking Tawstock with Barnstaple in North Devon, England, spanning the River Taw.  One of the largest medieval bridges in Britain, it is a Grade I listed building and ancient monument.  Another major medieval bridge, the Bideford Long Bridge over the Torridge, is a few miles away. 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. The Chantry Chapel of St Mary the Virgin, Wakefield, is a chantry chapel in Wakefield, West Yorkshire, England, and is designated a Grade I Listed building by English Heritage.  It is located south of the city centre on the medieval bridge over the River Calder.  It is the only survivor of four chantries in Wakefield and the oldest and most ornate of the surviving bridge chapels in England.  Others are at St Ives, Cambridgeshire, Rotherham and Bradford-on-Avon.  The chapel has had three west fronts, the original medieval façade having been removed to Kettlethorpe Hall in 1832.  The medieval bridge is a scheduled ancient monument. Loughor Castle is a ruined, medieval fortification located in the town of Loughor, Wales.  The castle was built around 1106 by the Anglo-Norman lord Henry de Beaumont, during the Norman invasion of Wales.  The site overlooked the River Loughor and controlled a strategic road and ford running across the Gower Peninsula.  The castle was designed as an oval ringwork, probably topped by wicker fence defences, and reused the remains of the former Roman fort of Leucarum. Portchester Castle is a medieval castle built within a former Roman fort at Portchester to the east of Fareham in the English county of Hampshire.  It is located at the northern end of Portsmouth Harbour.  Probably founded in the late 11th century, Portchester was a baronial castle taken under royal control in 1154.  The monarchy controlled the castle for several centuries and it was a favoured hunting lodge of King John.  It was besieged and captured by the French in 1216 before permanently returning to English control shortly thereafter. Bewcastle Roman Fort was a Roman fort, built to the north of Hadrian's Wall as an outpost fort and intended for scouting and intelligence.  The Roman name for the fort was Fanum Cocidi (as recorded in the Ravenna Cosmography), and means 'The Shrine of Cocidius', a deity worshipped in northern Britain.  The remains of the fort are situated at the village of Bewcastle, Cumbria, 7 mi to the north of the Roman fort at Birdoswald, on Hadrian's Wall.
