Welcome to Horse Guards, the official entrance to Buckingham Palace and St. James Palace. Look at the troops and their fancy outfits. The King’s Life Guard, conducted by soldiers of the Household Cavalry Mounted Regiment, obviously, gives the site its name. They belong to the two senior Regiments of the British Army, the Life Guards wearing red tunics and white plumed helmets, and the Blues and Royals wearing blue tunics and red plumed helmets. They have been guarding the King or Queen since the 17th century! Now, let’s talk a little bit about their magnificent black horses.
