The Roman Baths complex is a site of historical interest in the English city of Bath. The house is a well-preserved Roman site for public bathing.
The Roman Baths themselves are below the modern street level. There are four main features: the Sacred Spring, the Roman Temple, the Roman Bath House and the Museum holding finds from Roman Bath. The buildings above street level date from the 19th century.
The Baths are a major tourist attraction and, together with the Grand Pump Room, receive more than one million visitors a year. It was featured on the 2005 TV program Seven Natural Wonders as one of the wonders of the West Country. Visitors can see the Baths and Museum but cannot enter the water. An audio guide is available in several languages.
The water which bubbles up from the ground at Bath falls as rain on the nearby Mendip Hills. It percolates down through limestone aquifers to a depth of between 2,700 and 4,300 metres (8,900 and 14,100 ft) where geothermal energy raises the water temperature to between 64 and 96 °C (147.2 and 204.8 °F). Under pressure, the heated water rises to the surface along fissures and faults in the limestone.
