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.

Indo-Saracenic architecture was a revivalist architectural style mostly used by British architects in India in the later 19th century, especially in public and government buildings in the British Raj, and the palaces of rulers of the princely states. It drew stylistic and decorative elements from native Indo-Islamic architecture, especially Mughal architecture, which the British regarded as the classic Indian style. The basic layout and structure of the buildings tended to be close to that used in contemporary buildings in other revivalist styles, such as Gothic revival and Neo-Classical, with specific Indian features and decoration added.
