The Mount Street Gardens is a public garden off Mount Street in the west of the Mayfair area of London, created in 1889. They were created out of a former burial ground of St George's, Hanover Square, and named after the Mount Field, an area including a fortification dating from the English Civil War named Oliver's Mount.
The land was originally sold by Sir Richard Grosvenor, 4th Bart. to the Commission for Building Fifty New Churches in 1723 as part of his development of the area around Mount Street, to serve as a burial ground for the parish church, St. George's, located in Hanover Square. Beside the burial ground, on South Audley Street, was planned the Grosvenor Chapel, but this was not built until 7 years after the burial ground was laid out, in 1730.
To the north of the ground, the site of what is now 103 Mount Street, was the parish's workhouse, wherein the poor were given work, board, and lodgings, built in 1725 and then enlarged in the 1780s to provide room for the parish watchmen's watch-house and the parish office.
