Westminster Abbey, formally titled the Collegiate Church of St Peter at Westminster, is a large, mainly Gothic abbey church in the City of Westminster, London, just to the west of the Palace of Westminster. It is one of the United Kingdom's most notable religious buildings and the traditional place of coronation and burial site for English and, later, British monarchs. Between 1540 and 1556, the abbey had the status of a cathedral. Since 1560, however, the building is no longer an abbey nor a cathedral, having instead the status of a Church of England "Royal Peculiar"—a church responsible directly to the sovereign. The building itself is the original abbey church.
The Westminster Abbey Museum was located in the 11th-century vaulted undercroft beneath the former monks' dormitory in Westminster Abbey. This is one of the oldest areas of the abbey, dating back almost to the foundation of the church by Edward the Confessor in 1065. This space had been used as a museum since 1908.
