Windsor Castle

Windsor Castle is a royal residence, notable for its long association with the English and later British royal family and for its architecture. The original castle was built in the 11th century after the Norman invasion of England by William the Conqueror.
Since the time of Henry I, it has been used by the reigning monarch and is the longest-occupied palace in Europe. The castle State Apartments are considered by many historians as the finest and most complete expression of later Georgian taste.
It is a popular tourist attraction, a venue for hosting state visits, and the preferred weekend home of Elizabeth II. Today, more than 500 people live and work in Windsor Castle - the largest inhabited castle in the world.
