Horse Guards (building)

Horse Guards is a large grade I listed building in the Palladian style between Whitehall and Horse Guards Parade in London. The first Horse Guards building was built on the site of the former tiltyard of Westminster Palace in 1664.[1] It was demolished in 1749 and was replaced by the current building which was built between 1750 and 1753 by John Vardy after the death of original architect in 1748 William Kent.
