Inside a blue metal shelter are the foundations of a Roman Bath House, used for public bathing during the Roman occupation. The original bath house consisted of two rooms, the hot and warm baths; a third room with a cold bath and changing area was added later.
Some of the BBLHS visitors listen to Bromley Museum's Curator, Marie-Louise Kerr, describing the site and displaying some artefacts found there during the original excavations carried out by one of her predecessors in the 1970s.
