The Great Bath of the Roman Baths in Bath, England, with Bath Abbey in the background. The complex, a grade I listed building, was constructed during Roman Britain, during which time the town was known as Aquae Sulis. It was rediscovered in the 18th century and, as well as being a major archaeological find, it has become one of the city's main attractions. The entire structure above the level of the pillar bases is a later reconstruction.Photo credit: Diliff
