Some evidence found on site suggests that about A. D. 150, the villa was considerably enlarged and may have been used as the country retreat of the governors of the Roman province of Britannia. Two sculpted marble busts found in the cellar may be those of Pertinax, governor in 185-186, and his father-in-law, Publius Helvius Successus. In the 4th century a room, probably already in religious use, was converted to a Christian chapel or house church, much the earliest known in the British Isles.
