The grounds attached to the Royal Pavilion and Marlborough House were, originally, of very limited proportions, those to the east front consisting only of a narrow lawn west of a direct line northward from the east front of the houses that form the north-east corner of Castle Square, on the Steine. But in consideration of the Prince and the Duke constructing in 1793, the sewer to carry off the stream which flooded the Steine in winter, the Lords of the Manor,—Brighthelmston-Lewes—with consent of the homage, gave them permission to enclose a certain portion of the Steine,—the Marlborough Steine, as it was termed,—adjoining their houses respectively; but never to build or encumber it with anything that might obstruct the prospect, or be any way a nuisance to the Steine. The ground then taken in was parted from the Steine by park palings, and posts and rails were put along the outer side to form a foot-way for the public. In 1800, His Royal Highness purchased the principal portion of the Pavilion property to the south, of Mr. Weltjie, but no important improvements were undertaken until the following year, when, His Royal Highness having purchased the Elm Grove Gardens, the permission of the inhabitants was given him to enclose the old London Road, which ran direct northward from the top of East Street, on his making the New Road at his own expense. By this alteration, the Grove, and the shrubberies and pleasure-grounds of the Duke of Marlborough, which he likewise purchased, became united with the Pavilion Grounds. The Promenade Grove or Public Gardens, which were under the particular patronage of the Prince of Wales, occupied the space of the present Pavilion Grounds, directly south of the Royal Stables, as also the site of the stables, and were approached by way of Prince’s Place, an arched gateway occupying the space whereon stand the premises now occupied as the First Sussex Volunteer Rifle Orderly Room. Prince’s Place was intended chiefly for the accommodation of the London tradesmen who came to Brighton with their wares for the season. An enclosed shrubbery of small dimensions occupied the centre of the open space, and the carriage drive was about it.
