Thermae Bath Spa

Thermae Bath Spa is a combination of the historic spa and a contemporary building in the city of Bath, England, and re-opened in 2006. Bath and North East Somerset council own the buildings, and, as decreed in a Royal Charter of 1590, are the guardians of the spring waters, which are the only naturally hot, mineral-rich waters in the UK. The Spa is operated by Thermae Development Company.

The main spa building, the New Royal Bath, was designed by Grimshaw Architects and is constructed in Bath stone, enclosed by a glass envelope. It has two natural thermal baths, an open-air rooftop pool and an indoor pool, a large steam room with four circular glass pods and 20 spa treatment rooms, including the 18th century Hot Bath. The separate Cross Bath is a grade 1 listed Georgian building containing one open-air thermal bath.

History

One of the city's main attractions has long been its famous hot spa water, fed by the area's hot springs. The Bath springs are the warmest geothermal springs found in the UK. These natural geothermal mineral springs fed into the Roman Baths complex, which was responsible for the prominence of Bath in the Roman period, as well as for the later development of Bath as the country's leading eighteenth and early nineteenth century health resort. In the middle of the 20th century, the city's swimming pool sourced its water directly from the King's Spring through one of three pipelines beneath the River Avon. However, the old municipal hot pools were closed in 1978 after the discovery of an infectious organism in one stratum of the aquifer. After that date, bathing was prohibited.
