Sloane Square is a small hard-landscaped square on the boundaries of the fashionable London districts of Knightsbridge, Belgravia and Chelsea. The square lies at the east end of the trendy Kings Road and at the south end of the more conventionally smart Sloane Street linking to Knightsbridge. The Square has two notable buildings: Peter Jones department store and the Royal Court Theatre. The River Westbourne is carried over the tube station in a large iron pipe.

In early 2005 improvements to the square were proposed to make it more pedestrian friendly. Near it, are the National Army Museum and Holy Trinity Sloane Street, the basilica-like parish church known as the "Cathedral of the Arts & Crafts Movement", built in 1890 a few yards from the square itself.
