The Treasurer's House was originally just what it sounds like...the house for the Treasurer of York Minster. In 1547, at the time of the Reformation, the office of Treasurer was abolished and the house passed into many hands over the centuries. It was in a state of sad disrepair when it was purchased by Frank Green in 1897. He repaired the house with the help of architect Temple Moore, and restored the exterior to something like its original shape. Over the years, Green continually change and rearranged the furniture, and added to the decoration and fittings as his ideas about particular rooms developed. He designed each room to be of a specific period. When he retired in 1930 he gave Treasurer's House and all its contents to the National Trust. This was the first home received by the National Trust with all of its contents.
One of the things I found really fascinating about the house (besides the beautiful needlework and furniture), was that it is built on an ancient Roman road. People in the basement have seen ghosts of a Roman detachment of soldiers appear out of the wall, pass across the hallway, and disappear into the next wall!
