Windsor Castle, the largest and oldest occupied castle in the world, is one of the official residences of Her Majesty The Queen.

The Castle's dramatic site encapsulates 900 years of British history. It covers an area of 26 acres and contains, as well as a royal palace, a magnificent chapel and the homes and workplaces of a large number of people.

This view is only a part of the outer walls, as seen from the main street in Windsor but it does give a feel for it's age and historic architecture. The smaller view is of one of the side entrances, complete with gate-house cottage.
