The Queen's Guard and Queen's Life Guard (called King's Guard and King's Life Guard when the reigning monarch is male) are the names given to contingents of infantry and cavalry soldiers charged with guarding the official royal residences in the United Kingdom. The British Army has regiments of both Horse Guards and Foot Guards predating the English Restoration (1660), and since the reign of King Charles II these have been responsible for guarding the Sovereign's palaces. Contrary to popular belief, they are not purely ceremonial and are operational-duty soldiers armed with functional firearms loaded with live ammunition.
Windsor (/ˈwɪnzər/) is a town and unparished area in the Royal Borough of Windsor and Maidenhead in Berkshire, England. It is widely known as the site of Windsor Castle, one of the official residences of the British Royal Family. The town is situated 23 miles (37 km) west of Charing Cross, London. It is immediately south of the River Thames, which forms its boundary with Eton. The village of Old Windsor, just over 2 miles (3 km) to the south, predates what is now called Windsor by around 300 years; in the past Windsor was formally referred to as New Windsor to distinguish the two.
