Horse Guards is a magnificent, palatial, Grade I listed building that can be found in London, between Horse Guards Palace and Whitehall. It was originally built in 1664, on the former jousting courtyard (also known as a tiltyard) of Westminster Palace, and was designed in the growingly popular Palladian style of the time (a European style inspired by the Venetian architect Andrea Palladio). However, this original structure was demolished just 75 years later, to be replaced by the building that we see today, which was designed by William Kent and built by John Vardy. It took Vardy just two years, from 1751 to 1753, to complete the building as we see it today.
For the next 151 years, the Horse Guards building was used as the offices of the Commander-in-Chief of the Forces (the head of the British Army), until the post was disestablished in 1904. The offices were then used by the Chief of the General staff for two years, before he moved the the Old Office War building in 1906, and the Horse Guards switched hands once again, to be used by the London district and the Household Cavalry.
These days, in the centre of the Horse Guards building, lies the Household Cavalry Museum, which boasts a 'behind the scenes' feature unlike any other museum - revealing to the public the intricate work that goes into the ceremonial and operational role of the Household Cavalry Regiment. Entry to the Museum is £6 for adults and £4 for children.
