At the 2021 census, the population was 94,092. Bath is in the valley of the River Avon, 97 miles (156 km) west of London and 11 miles (18 km) southeast of Bristol. The city became a Unesco World Historic Site in 1987, and was later added to the transnational World Historic Site known as the "Great Spa Towns of Europe" in 2021. Bath represents also the largest city and settlement in Somerset. The city became a spa with the Latin name Aquae Sulis ("the waters of 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, boasts the Royal Crescent, Circus, Pump Room, and the 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. 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. Bath has over 6 million yearly visitors, making it among the ten English cities visited most by overseas tourists.
