The Strand Lane Baths, at 5 Strand Lane, London WC2R 2NA, have been reputed since the 1830s to be a Roman survival.  They are in fact the remaining portion of a cistern built in 1612 to feed a fountain in the gardens of the old Somerset House, then a royal place.  After a long period of neglect and decay, following the demolition of the fountain, they were brought back into use in the 1770s as a public cold plunge bath, attached to No 33 Surrey Street.  The idea that they were Roman probably began some fifty years later as an advertising gimmick, and has aroused both enthusiasm and scepticism ever since.
