Treasurer's House in York, United Kingdom, is a historic building located behind York Minster. It was originally built in the 11th century as the home for the Treasurer of York Minster. Over the centuries, the house has been rebuilt and modified, resulting in a blend of architectural styles from medieval to the Edwardian era. Frank Green, a wealthy local industrialist, acquired the property in the late 19th century and restored it. In 1930, he gave it to the National Trust, complete with a collection of fine antiques and furnishings. The house is now a museum showcasing elaborate period rooms, including a grand hall, a drawing-room, a blue salon, and the famous haunted cellars. The Treasurer's Garden is a tranquil spot, offering views of the Minster and a relaxing retreat from the bustling city. The house is reputed to have multiple ghosts, and the cellars are a popular spot for ghost tours. Visitors can enjoy guided tours that reveal the history of the house, including stories about its former residents and the restoration efforts by Green.
