Windsor Castle is on the Thames River. It is a very big and very old castle. English kings and queens have lived here since the 11th century. There are rooms for receptions and for important visitors. There are also apartments for the queen,a library and a big park. When the queen is there, part of castle is closed for visitors.
Near the castle is the famous school Eton,which is also very old (1440). Over a thousand boys go to this school. They are twelve or thirteen when they start here,and they stay until they go to university.
