Normally open during the summer months, the remarkable Roman Painted House was excavated by the Kent Archaeological Rescue Unit in the 1970s. This town house, dating from 200A.D., plus a section of a major Roman fort, dating from 270A.D. has been preserved within a modern building. No comparable painted walls have survived north of the Alps. The hypocaust (underfloor) heating system can be seen and there are displays of artefacts, photographs and a video.
