Billingsgate Roman House and Baths is an archaeological site in Londinium. The best preserved parts of the house are a bath with hypocausts. The ruins of the tepidarium were discovered in 1848 while the Coal Exchange was built on the site. Its preservation on the instruction of J. B. Brunning is the earliest example of in situ preservation in the City of London. The remains were preserved and were visible in the cellar of the building.
