Windsor Castle in England is the world’s largest inhabited castle. It is also the longest-inhabited castle in the world, as the only medieval castle with residents since the Middle Ages until the present day, without any interruption.
This property of 45,000 square meters belongs to the Queen of England, and is one of her three official residences, alongside Buckingham Palace in London and Holyrood Palace in Edinburgh. The Queen spends almost every weekend at Windsor Castle.
Built in 1070-1080 by William the Conqueror (1066-1087) mainly for defense purposes, it began to be used as royal residence in 1110 by King Henry I. His son, Henry II, turned the castle into a complex of residential buildings which Henry III, his successor, continued work on from 1227 onwards. A century later, in 1350, Edward III resumed work on the palace.
Almost every king and queen of England has left a mark on Windsor, adding new features in times of peace and fortifying it at wartime, or decorating it with works of art and paintings by some of the world’s most valuable artists.
