Bath. Bath is the largest city in the county of Somerset, England, known for and named after its Roman-built baths. In 2011, the population was 88,859. Bath is in the valley of the River Avon, 97 miles west of London and 11 miles southeast of Bristol. The city became a World Heritage site in 1987. The city became a spa with the Latin name Aquae Sulis c. 60 AD when the Romans built baths and a temple in the valley of the River Avon, although hot springs were known even before then. Bath Abbey was founded in the 7th century and became a religious centre; the building was rebuilt in the 12th and 16th centuries. In the 17th century, claims were made for the curative properties of water from the springs, and Bath became popular as a spa town in the Georgian era. Georgian architecture, crafted from Bath stone, includes the Royal Crescent, Circus, Pump Room and Assembly Rooms where Beau Nash presided over the city's social life from 1705 until his death in 1761. Many of the streets and squares were laid out by John Wood, the Elder, and in the 18th century the city became fashionable and the population grew. Jane Austen lived in Bath in the early 19th century. Further building was undertaken in the 19th century and following the Bath Blitz in World War II. The city has software, publishing and service-oriented industries. Theatres, museums and other cultural and sporting venues have helped make it a major centre for tourism, with more than one million staying visitors and 3.8 million day visitors to the city each year. There are several museums including the Museum of Bath Architecture, the Victoria Art Gallery, the Museum of East Asian Art, the Herschel Museum of Astronomy, Fashion Museum, and the Holburne Museum. The city has two universities-the University of Bath and Bath Spa University-with Bath College providing further education. Sporting clubs include Bath Rugby and Bath City F.C. Bath became part of the county of Avon in 1974, and, following Avon's abolition in 1996, has been the principal centre of Bath and North East Somerset. Aquae Sulis The hills in the locality such as Bathampton Down saw human activity from the Mesolithic period. Several Bronze Age round barrows were opened by John Skinner in the 18th century. Solsbury Hill overlooking the current city was an Iron Age hill fort, and the adjacent Bathampton Camp may also have been one. A long barrow site believed to be from the Beaker people was flattened to make way for RAF Charmy Down. Archaeological evidence shows that the site of the Roman baths' main spring may have been treated as a shrine by the Britons, and was dedicated to the goddess Sulis, whom the Romans identified with Minerva; the name Sulis continued to be used after the Roman invasion, appearing in the town's Roman name, Aquae Sulis. Messages to her scratched onto metal, known as curse tablets, have been recovered from the sacred spring by archaeologists. The tablets were written in Latin, and cursed people whom the writers felt had wronged them. For example, if a citizen had his clothes stolen at the baths, he might write a curse, naming the suspects, on a tablet to be read by the goddess. A temple was constructed in AD 60-70, and a bathing complex was built up over the next 300 years. Engineers drove oak piles into the mud to provide a stable foundation, and surrounded the spring with an irregular stone chamber lined with lead. In the 2nd century, the spring was enclosed within a wooden barrel-vaulted structure that housed the caldarium, tepidarium, and frigidarium. The town was later given defensive walls, probably in the 3rd century. After the failure of Roman authority in the first decade of the 5th century, the baths fell into disrepair and were eventually lost as a result of rising water levels and silting. In March 2012 a hoard of 30,000 silver Roman coins, one of the largest discovered in Britain, was unearthed in an archaeological dig. The coins, believed to date from the 3rd century, were found about 150 m from the Roman baths. Bath may have been the site of the Battle of Badon, in which King Arthur is said to have defeated the Anglo-Saxons. The town was captured by the West Saxons in 577 after the Battle of Deorham; the Anglo-Saxon poem The Ruin may describe the appearance of the Roman site about this time.
