Condercum Condercum was a Roman fort at modern - day Benwell , a suburb of Newcastle upon Tyne , England . It was the third fort on Hadrian ' s Wall , after Segedunum ( Wallsend ) and Pons Aelius ( Newcastle ) , and was situated to the west of the city . Today , nothing can be seen of the fort or its adjoining wall , as the site is covered by buildings and is crossed by the A186 Newcastle to Carlisle road . The remains of a small temple dedicated to Antenociticus , a local deity , can be seen nearby , and the original causeway over the vallum , or ditch , can also be seen . Description . The remains of the fort lie on Hadrian ' s Wall to the west of Newcastle . The fort measured from north to south by east to west and the defences enclosed an area of just over . It was a cavalry fort , and had three gates leading to the north of the wall . There were two side gates , facing east and west , through which the Roman military road , running along the south side of the wall , entered and exited . There was also a south - facing gate that led to a causeway that crossed the vallum . The causeway had a gateway , halfway across which was closed by doors . The fort contained a commandant ’ s house , headquarters , two granaries , workshops , barracks , stables and a hospital . Construction and garrison . It is known from several building inscriptions that the defences of the fort at Benwell were built by soldiers from the Second Augustan Legion ( Legio II Augusta ) . It is believed that it was built between 122 AD and 124 AD . Soldiers from the Twentieth Legion ( Legio XX Valeria Victrix ) were apparently responsible for some additional building or repair work at Benwell in the late - 2nd century . The fort contained two granaries , and it is known that these were built by a detachment from the British Fleet , probably because the legionnaires responsible for construction of the fort had been called away . It is likely that the detachment was sent from nearby Arbeia , in modern - day South Shields . In the 2nd century Condercum was garrisoned by the Cohors I Vangionum Milliaria Equitata , which was a part - mounted unit from Upper Germany . This had a nominal strength of one thousand men , but it is likely that only half of this number occupied the fort . It is thought that from AD 205 to AD 367 , a five - hundred - strong auxiliary cavalry unit ( Ala Primae Hispanorum Asturum ) , from the Astures tribe in northern Spain , was stationed at the fort . Other buildings . There is evidence that a village , or vicus , grew up around the fort , lying to the north and south of the vallum . The remains of three notable buildings were found near the fort . A number of altar - stones have been found at the site , dedicated to various gods . Three of the altars were dedicated to Antenociticus , who is believed to be a Celtic deity . A hundred yards to the east of the fort , the remains of a temple dedicated to Antenociticus , believed to be a local Celtic deity , can still be seen . The building , which was discovered in 1862 , measures from east to west and from north to south , with an apse extending a further six feet on the south end . It is believed that the apse contained a life - size statue of the god , as a full size head was found , together with the fragments of an arm and a leg . The head was adorned with a Celtic neck torc . The temple also contained three altars to Antenociticus . Three hundred yards to the southwest of the fort , a bathhouse was discovered in 1751 . The building had several rooms , which were probably the hot and cold rooms and dressing rooms normally found in such bathhouses . Just south of the vallum causeway , a third building was found . This was a large domestic building , believed to be a mansio , or resthouse for official travellers .
