It was put up for sale in 1910. Its greatest treasures, the huge medieval fireplaces, were still intact. When an American bought them they were ripped out and packaged up for shipping. Lord Curzon of Kedleston stepped in at the eleventh hour to buy the castle and was determined to get the fireplaces back. After a nationwide hunt they were found in London and returned. He restored the castle and left it to the National Trust on his death in 1925. Lord Curzon had undertaken restorations on it between 1911 and 1914. It remains today one of the three most important surviving brick castles of the mid-15th century.
