Crofton Roman villa

Crofton Roman Villa in Crofton, Orpington, in the London Borough of Bromley, is a Roman villa which was inhabited between approximately 140 and 400 AD. It was the centre of a farming estate of about 500 acres, with farm buildings nearby, surrounded by fields, meadows and woods. The house was altered several times during its 260 years of occupation, and at its largest it probably had at least 20 rooms.

The remains of ten rooms can be seen today. Two rooms contain the remains of "opus signinum" floors, and three have evidence of tiled, or "tessellated", floors. Details of an underfloor central heating hypocaust can also be seen, featuring both channelled and pillared systems, as can small finds from the site.
