Longovicivm, Durham

Longovicivm (or Lanchester Roman Fort) was an auxiliary fort in County Durham. It is located on the roman road 'Dere Street' (in the Roman province of Britannia Inferior) about one mile south-west of Lanchester. The fort is estimated to have been built later than the other forts on Dere Street, around AD 150. There is evidence it was rebuilt around AD 230/240 and again in the early 4th century. A construction slab identifies the Legio XX Valeria Victrix (Twentieth Legion) as having built the fort.The fort was an estimated 525 feet by 460 feet in size and accommodated approximately 1,000 troops. The fort was occupied from AD 160 until 400 and there was an associated civil settlement (vicus) associated with the fort with buildings on both sides of Dere Street. It is within the council area of County Durham. More...

Longovicium is also interesting in having a copious water supply from two aqueducts, one of which was fed from an impounded source to the west. The dam harnessed the water of 21 springs and was 20 feet high and 110 yards in length, being stone faced and clay lined on the inside. Despite not being on the scale of those supplying cities, the Longovicium aqueduct was nevertheless a significant feat of engineering, being considered one of the best preserved aqueducts in Britain.
