The Crofton Roman Villa house was occupied from about AD 140 to 400 and was the centre of a farming estate of about 500 acres. Nearby would have been farm buildings, surrounded by fields, meadows and woods.
The house was altered several times during its 260 years of occupation and at its largest probably had at least 20 rooms. The remains of ten rooms can be seen today, now within a modern cover building. Two rooms contain the remains of their opus signinum (concrete) floors, and three have evidence of tessellated (tiled) floors. Details of the under-floor central heating (hypocaust) can be seen, which features both channelled and pillared systems.
The site was fully excavated by the Kent Archaeological Rescue Unit which also carried out the complete preservation scheme, with funding provided by Bromley Council. The Unit now manages the scheme in conjunction with the Council.
