If a castle can be called a house in the biggest one lives the British queen Elizabeth II (on the throne since 1952). Windsor is one of the most important castles of the English royalty. A 45.000 square meters castle with over one thousand rooms stands on a five hectares ground. This castle holds two other records: it is the oldest in the world and in continuous use since William the Conqueror (1066-1087). Windsor has been reconstructed and redesigned several times according to its owners’ style.
