The barracks were built in the early nineteenth century. From 1896 to 1969, the Royal Horse Guards were based there, which later became part of the Blues and Royals. With the formation of the Household Cavalry Mounted Regiment in 1991, the Blues and Royals moved to Hyde Park Barracks, Knightsbridge. Today it is the base of 20 Transport Squadron, Royal Logistic Corps, the Artists Rifles and The Regimental Headquarters of the Queen's Royal Hussars, as well as the charity "The Queen's Royal Hussars Collection Trust". In 1971 an anarchist group called The Angry Brigade bombed the barracks. One of the members was held here for a time. Over the top of the entrance there is the legend "Regents Park Barracks", but outside of officialdom, it is almost always referred to as the Albany Street Barrack
