The Royal Pavilion, and surrounding gardens, also known as the Brighton Pavilion, is a Grade I listed former royal residence located in Brighton, England. Beginning in 1787, it was built in three stages as a seaside retreat for George, Prince of Wales, who became the Prince Regent in 1811, and King George IV in 1820. It is built in the Indo-Saracenic style prevalent in India for most of the 19th century. The current appearance of the Pavilion, with its domes and minarets, is the work of architect John Nash, who extended the building starting in 1815. George IV's successors William IV and Victoria also used the Pavilion, but Queen Victoria decided that Osborne House should be the royal seaside retreat, and the Pavilion was sold to the city of Brighton in 1850.

Brighton is a seaside resort and one of the two main areas of the city of Brighton and Hove in the county of East Sussex, England. It is located 47 miles (76 km) south of London. Archaeological evidence of settlement in the area dates back to the Bronze Age, Roman and Anglo-Saxon periods. The ancient settlement of "Brighthelmstone" was documented in the Domesday Book (1086). The town's importance grew in the Middle Ages as the Old Town developed, but it languished in the early modern period, affected by foreign attacks, storms, a suffering economy and a declining population. Brighton began to attract more visitors following improved road transport to London and becoming a boarding point for boats travelling to France. The town also developed in popularity as a health resort for sea bathing as a purported cure for illnesses.
