 At the end of this period Windsor Castle became a place of royal confinement. In 1788 the king first became ill during a dinner at Windsor Castle; diagnosed as suffering from madness, he was removed for a period to the White House at Kew, where he temporarily recovered. After relapses in 1801 and 1804, his condition became enduring from 1810 onwards and he was confined in the State Apartments of Windsor Castle, with building work on the castle ceasing the following year.
