Royal Crescent in the context of John Wood, the Younger

Bath (RP: /bɑːθ/, locally [ba(ː)θ]) is a city in Somerset, England, known for and named after its Roman-built baths. 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 Heritage Site in 1987, and was later added to the transnational World Heritage Site known as the "Great Spa Towns of Europe" in 2021. Bath is 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, includes 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.

The Bath Assembly Rooms, designed by John Wood, the Younger in 1769, are a set of assembly rooms located in the heart of the World Heritage City of Bath in England which are now open to the public as a visitor attraction. They are designated as a Grade I listed building.

During the Georgian era Bath became fashionable, and the architects John Wood, the Elder, and his son laid out new areas of housing for residents and visitors. Assembly rooms had been built early in the 18th century, but a new venue for balls, concerts and gambling was envisaged in the area between Queen Square, The Circus and the Royal Crescent. Robert Adam submitted a proposal that was rejected as too expensive. John Wood, the Younger raised funding through a tontine, and construction started in 1769. The new or upper assembly rooms opened with a grand ball in 1771 and became the hub of fashionable society, being frequented by Jane Austen and Charles Dickens, along with the nobility of the time.
