Windsor (/ˈwɪnzər/) is a town and unparished area in the Royal Borough of Windsor and Maidenhead in Berkshire, England. It is widely known as the site of Windsor Castle, one of the official residences of the British Royal Family. The town is situated 23 miles (37 km) west of Charing Cross, London. It is immediately south of the River Thames, which forms its boundary with Eton. The village of Old Windsor, just over 2 miles (3 km) to the south, predates what is now called Windsor by around 300 years; in the past Windsor was formally referred to as New Windsor to distinguish the two.
Windsor Castle is a royal residence at Windsor in the English county of Berkshire. The castle is notable for its long association with the English and later British royal family and also for its architecture. The original castle was built in the 11th century after the Norman invasion by William the Conqueror. Since the time of Henry I, it has been used by succeeding monarchs and is the longest-occupied palace in Europe. The castle's lavish, early 19th-century State Apartments are architecturally significant, described by art historian Hugh Roberts as "a superb and unrivalled sequence of rooms widely regarded as the finest and most complete expression of later Georgian taste". The castle includes the 15th-century St George's Chapel, considered by historian John Martin Robinson to be "one of the supreme achievements of English Perpendicular Gothic" design. More than 500 people live and work in Windsor Castle.
