It is roughly defined by a triangle formed by the Brompton Cemetery, Old Brompton Road/Brompton Road and Walton Street/Fulham Road.
Charles Dickens, Jr. (eldest child of Charles Dickens) wrote in his 1879 book Dickens's Dictionary of London that "[Brompton] was at one time almost exclusively the artist quarter and is still largely frequented by the votaries of the brush and chisel, though of late years Belgravia has been encroaching upon its boundaries, and Belgravian rents are stealing westward."
