Windsor Castle is a royal residence at Windsor in the English county of Berkshire. The castle is notable for its long association with the British royal family and 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 it is the longest-occupied palace in Europe.
Edward IV seized power in 1461. When Edward captured Henry's wife, Margaret of Anjou, she was brought back to be detained at the castle. Edward began to revive the Order of the Garter, and held a particularly lavish feast in 1472. Edward began the construction of the present St. George's Chapel, Windsor in 1475, resulting in the dismantling of several of the older buildings in the Lower Ward. By building the grand chapel Edward was seeking to show that his new dynasty were the permanent rulers of England, and may also have been attempting to deliberately rival the similar chapel that Henry VI had ordered to be constructed at nearby Eton College. Richard III made only a brief use of Windsor Castle before his defeat at the Battle of Bosworth Field in 1485, but had the body of Henry VI moved from Chertsey Abbey in Surrey to the castle to allow it to be visited by pilgrims more easily.
Henry VII made more use of Windsor. In 1488, shortly after succeeding to the throne, he held a massive feast for the Order of the Garter at the castle. He completed the roof of St George's Chapel, and set about converting the older eastern Lady Chapel into a proposed shrine to Henry VI, whose canonisation was then considered imminent. In the event, Henry VI was not canonised and the project was abandoned, although the shrine continued to attract a flood of pilgrims. Henry VII appears to have remodelled the King's Chamber in the palace, and had the roof of the Great Kitchen rebuilt in 1489. He also built a three-storied tower on the west end of the palace, which he used for his personal apartments
