Regency Square is a large early 19th-century residential development on the seafront in Brighton, part of the British city of Brighton and Hove. Conceived by speculative developer Joshua Hanson as Brighton underwent its rapid transformation into a fashionable resort, the three-sided "set piece" of 69 houses and associated structures was built between 1818 and 1832. Most of the houses overlooking the central garden were complete by 1824. The site was previously known, briefly and unofficially, as Belle Vue Field. The square was a prestigious, high-class development, attracting the social elite. The central garden, originally private, has been council-owned since 1885 and publicly accessible since WW2. An underground car park was built beneath it in 1969. Most of the buildings in and around the square have been designated Listed buildings: 47 houses are each listed at Grade II*, the second-highest designation, while 18 other houses, a war memorial, a nearby inn and a set of bollards outside it have each been given the lower Grade II status. The house at the southwest corner is now numbered as part of King's Road but was built as part of Regency Square, and is also Grade II*-listed.

The windmill was owned by Matthew Bourne in 1744, but was not marked on Ogilby's 1762 map, although a windmill is shown on Lambert's View of Brighthelmstone which is dated 1765. In the 1790s, the windmill was owned by John Streeter. On 28 March 1797, when 86 oxen dragged it uphill on a sled to the nearby village of Preston. It was re-erected there and renamed Preston Mill. After several more renamings, it was demolished in 1881. Its machinery was cannibalised by the owners of nearby Waterhall Mill. A watercolour painting, now displayed at Preston Manor, shows crowds of people watching the mill's removal to Preston. By the late 18th century, Brighthelmstone (as it was originally known) had begun to develop into a fashionable coastal resort.
