A row of terraced houses on Bathwick Hill in the city of Bath. Like much of the city the houses are built using the local golden-coloured Bath stone, a type of limestone. Located in south-west England, Bath is notable for its baths fed by three hot springs. It was first recorded as a Roman spa and temple named Aquae Sulis, although archaeological evidence suggests that the main spring of the baths may have been treated as a shrine by the Britons before the Roman invasion. From Elizabethan to Georgian times it was a resort city for the wealthy. As a result of its popularity during the latter period, the city contains many fine examples of Georgian architecture, particularly the Royal Crescent.Photograph: David Iliff
