During a series of extensive rescue excavations, ahead of development in Dover’s town centre undertaken by Kent Archaeological Rescue Unit, the remains of a large scale Roman structure were revealed and have been interpreted as being part of the eastern section of the south range of a mansio. Beneath the opus signinum floor of room 9 of this structure, which was located on the central section of this building, was a hypocaust constructed of chalk blocks, clay and tiles set out in 8 radiating channels leading to a central chamber.
