Reconstruction of Portchester Castle in AD 330, Portchester, Hampshire
Reconstruction drawing showing Portchester as it might have looked around AD 330. Archaeological excavations suggest the Roman fort at Portchester was built between AD 285-290. It's building probably relates to a series of 'barbarian' (Saxon) attacks along the coasts of Britain and Gaul (France) at this time. These were a problem for the Roman Empire and to combat them they built numerous forts on both sides of the Channel. This site is now in the care of English Heritage (2011). Find out more.
