Soon after the Roman invasion of Britain in 43 AD the 2nd Augustan legion marched from the south of the country crossing the Kennet Valley at Thatcham. A road was constructed from Silchester, through the Wasing Park area, crossing the Kennet, probably at first by a ford and later by a bridge, passing through the Midgham marsh (the remains of the ancient lake) through Thatcham.
During the second or third century AD the Romans established a large village in the area of Henwick Lane and Roman Way in Thatcham. Excavations of the site were carried with foundations of buildings; pottery, tiles, household implements and coins being unearthed. Several flint lined Roman wells have also been discovered in the area.
Early in the fifth century AD the Roman legions were withdrawn from Britain to face the Barbarian hordes who were threatening the imperial City itself.
