Portobello Public Baths were designed by Robert Morham, working for the Edinburgh City Architect’s Department of Edinburgh Council, in 1898, as part of the agreement that Portobello should become part of Edinburgh (on 1st November 1896). They were opened in 1901. Through most of the century they used to have a sea water pool and a fresh water pool (in the 1980s I used to belong to a sub-aqua club that used the sea water pool on Monday nights for training), but both pools are fresh water now. The Turkish baths were original to the building and are magnificent.
