Queen Anne’s Gate runs from Old Queen Street in the east to a cul-de-sac in the west. It runs parallel with Birdcage Walk to the north and Petty France, Broadway and Tothill Street to the south. Carteret Street joins Queen Anne’s Gate on its southern side.
Queen Anne's Gate is formed from two older streets, Park Street, part of the Christ's Hospital estate, and Queen Square, developed by the South Sea Company. In 1874, Park Street and Queen Square were renumbered and renamed Queen Anne's Gate.
There was a chapel at 50 Queen Anne's Gate, built in 1706 as a private chapel to serve the residents of Queen Square. By 1870, it had become a charitable school, and later served as a mission hall and a police institute. By 1890, it had become offices. The site is now occupied by the modern Ministry of Justice building.
