The Roman baths complex is a well-preserved site that was used for Roman bathing. The temple was constructed in 60-70 AD and the bathing complex was gradually built up over the next 300 years.

The water which bubbles up from the ground at Bath, fell as rain on the nearby Mendip Hills. It percolates down through limestone aquifers to a depth of between 2,700 metres (8,900 ft) and 4,300 metres (14,100 ft) where geothermal energy raises the water temperature to between 64 °C (147.2 °F) and 96 °C (204.8 °F). Under pressure, the heated water rises to the surface along fissures and faults in the limestone.
