Windsor Castle is another of The Queen’s official residences, and where she spends most weekends. Originally built as a fortress by William the Conqueror, the Castle is considered the largest inhabited castle in the world, and the oldest continually occupied. Within the Castle is St George’s Chapel, the site of many royal weddings through the years, and the home of the Most Noble Order of the Garter. It is here that the annual Garter Day service and procession take place.
In the surrounding Home Park and Windsor Great Park are many current and former royal residences, including Royal Lodge, Frogmore House, Cumberland Lodge, and Fort Belvedere (amongst others).
