Thirty-nine (39) Bridge Street, Chester

A Grade I listed building in Chester, England, notable for the remains of a 2nd-century Roman hypocaust in its cellar, discovered during reconstruction of the property in 1864. The heating system consists of 27 square columns in a chamber that originally held 32 columns in eight rows of four, and was part of the legionary baths complex used by soldiers of the Twentieth Legion. In the late 13th or early 14th century, a medieval undercroft was built adjacent to the hypocaust. Today the ground floor operates as a cafe with cellar access for visitors.
