Windsor is a town in Berkshire, south-east England, situated on the River Thames west of London. It is noteable as the location of Windsor Castle, a royal residence and the largest inhabited castle in Europe. The town is bounded to the east by Windsor Great park (a royal park attached to the castle), while the small town of Eton, connected to Windsor by a bridge over the Thames, is the location of Eton College, the most prestigious public (US: private) school in the United Kingdom.
