Located 97 miles west of London and 13 miles southeast of Bristol, Bath is a city in the ceremonial county of Somerset in southwest England. It was first established as a spa resort with the Latin name, Aquae Sulis ("the waters of Sulis"), by the Romans in AD 43 although verbal tradition suggests that Bath was known before then. The Romans built baths and a temple on the surrounding hills of the city in the valley of the River Avon around hot springs, which are the only ones naturally occurring in the United Kingdom. Much later, it became popular as a spa resort during the Georgian era, which led to a major expansion that left a heritage of exemplary Georgian architecture crafted from Bath Stone. Bath was granted city status by Royal Charter by Queen Elizabeth I in 1590. Edgar was crowned king of England at Bath Abbey in 973. The City of Bath became a World Heritage Site in 1987.
