The first Horse Guards building was commissioned by King Charles II in 1663, on the site of a cavalry stables which had been built on the tiltyard of the Palace of Whitehall during the Commonwealth. Built of red brick and costing some £4,000, it comprised a central range with a clock tower, under which an arch connected Whitehall with St James's Park; two wings enclosed a courtyard with two large sentry boxes for mounted troopers on the Whitehall side, facing the palace gate. Entry to the park, then an enclosed private garden, was controlled by special ivory passes issued to favoured courtiers, a tradition which continues to the present, although the modern passes are made of plastic; only the monarch has the right to drive through the arch without a pass. Initially, the building was intended only to accommodate the King's Guard and included stabling for more than a hundred cavalry horses on the ground floor, as well as separate barracks for the foot guards. Following a fire at Whitehall in 1698, the court transferred to St James's Palace, therefore the function of Horse Guards changed to controlling the ceremonial approach to St James's from Westminster. 's design for the new Horse Guards, dated 1750, the year that work commenced but after Kent's death. In the following decades, Horse Guards was increasingly used as administrative offices for the growing regular army and soon became overcrowded. The fabric of the building was also allowed to deteriorate; pieces of falling masonry were said to be a danger to the sentries. In 1745, King George II commissioned a new building in the fashionable Palladian style by the architect William Kent. Having to reuse the same plot of land, Kent managed to retain essentially the same plan as the original building while doubling the interior space. Kent died in April 1748 before the old Horse Guards had been demolished; work on the new building commenced in 1750 under the direction of Kent's assistant, John Vardy and William Robinson from the Office of Works. The cost of the buildings was £65,000 and took nearly ten years to complete. The Household Cavalry moved into the northern wing of the uncompleted building in 1755; at that time, there was stabling for 62 horses compared to 17 today. Originally, the two wings were connected to the central block by single storey ranges; in 1803-5 a further two floors were added to these, giving the building its present appearance. The building also served as the offices for the various administrative departments responsible to the Secretary at War, which would eventually become formalised as the War Office. Also located at Horse Guards was the office of the Commander-in-Chief of the Forces.. Two famous occupants of the office, a room originally intended for courts-martial, were Prince Frederick, Duke of York and Albany, popularly believed to be "The Grand Old Duke of York", and the Duke of Wellington. The final Commander-in-Chief at Horse Guards was Prince George, Duke of Cambridge, who was so reluctant to move to the new War Office building at Cumberland House in Pall Mall that he had to be ordered to leave by Queen Victoria. Wellington's desk is preserved in the same room, which is now the office of the Major-General Commanding the Household Division and General Officer Commanding London District. Horse Guards subsequently became the headquarters of two major Army commands: the London District and the Household Cavalry.
Horse Guards Clock
The clock is sited in the turret above the main archway; it has two faces, one facing Whitehall and the other, Horse Guards Parade, each dial being 7 feet 5 inches in diameter. It strikes the quarter-hours on two bells. Originally made by Thwaites in 1756, the clock was rebuilt in 1815–16 by Benjamin Lewis Vulliamy, the clockmaker to King George III. Prior to the completion of the clock of Big Ben in 1859, the Horse Guards Clock was the main public clock in Westminster. A dark stain above the Roman number two on the clock face is supposed to mark the time of the execution of King Charles I in 1649, which took place in the roadway outside Horse Guards. The annual ceremony of Trooping the Colour commences when the Horse Guards Clock strikes eleven.
Household Cavalry Museum
The Household Cavalry Museum is the official museum of the Household Cavalry and is located in the Horse Guards. Visitors can view the horses in the 18th-century working stables through a glazed partition. Exhibits explain the training and history of the regiment and include ceremonial uniforms, regalia, royal standards, awards, musical instruments, horse furniture and silverware by Fabergé. Visitors to the museum are welcome to watch the afternoon inspection of the guards and horses that happens daily at 4pm. This routine began in 1894 when Queen Victoria found the guards drinking and gambling in the afternoon instead of tending to their duty. She proclaimed that they would be punished by a four o'clock inspection daily for the next 100 years. This proclamation and punishment officially expired in 1994, but Queen Elizabeth II chose to continue the inspection out of respect for tradition.
