Bridge Street Number 39, Chester

39 Bridge Street is a Grade I listed building in Chester, England, remarkable for preserving a Roman hypocaust in its cellar dating to the 2nd century AD. The heating system consists of 27 surviving square pillar columns (originally 32 in eight rows) and formed part of the legionary bathhouse serving the Twentieth Legion. Discovered during reconstruction in 1864, the hypocaust is one of the best-preserved in situ Roman remains in Chester. Above ground, the four-storey building incorporates a medieval undercroft from the late 13th or 14th century and a section of the distinctive Chester Rows at first-floor level.
