Green Park, London in the context of Constitution Hill, London

Spring Gardens is a dead-end street at the south east extreme of St. James's, London, England, that crosses the east end of The Mall between Admiralty Arch and Trafalgar Square. Part of the old liberty of Westminster and the current City of Westminster, it abuts Whitehall, Horse Guards Parade, Green Park, and the Charing Cross/Strand/Trafalgar Square locality.

It is named after the gardens that stood here. These featured a decorative fountain in the time of Elizabeth I that was set in motion by passers-by treading on hidden machinery, knowingly or unknowingly. Mostly Victorian buildings have been built lining the street.

The King's Troop, Royal Horse Artillery, is a ceremonial unit of the British Army, quartered at Woolwich. It is a mounted unit and all of its soldiers are trained to care for and drive teams of six horses, each team pulling a First World War-era QF 13-pounder gun; six teams are used in the unit's Musical Drive. The Troop's duties include firing salutes on royal and state occasions, participation in parades, and the duties of the King's Life Guard at Horse Guards for one month each year. The unit provides the gun carriage and team of black horses for state funerals. The unit is most often seen providing gun salutes on state occasions in Hyde Park, and Green Park.
