wife. Lady Rowan later recalled, "It was sad to see such a great man become so frail". The following week, increasingly incapacitated, Churchill left the house for the last time. His official biographer Martin Gilbert records Churchill was, "never to see his beloved Chartwell again". After his death in January 1965, Lady Churchill relinquished her rights to the house and presented Chartwell to the National Trust. It was opened to the public in 1966, one year after Churchill's death. National Trust: 1966 to the present The house has been restored and preserved as it looked in the 1920–30s; at the time of the Trust's purchase, Churchill committed to leave it, "garnished and furnished so as to be of interest to the public". Rooms are decorated with memorabilia and gifts, the original furniture and books, as well as honours and medals that Churchill received. Lady Churchill's long-time secretary, Grace Hamblin, was appointed the first administrator of the house. Earlier in her career, Miss Hamblin had undertaken the destruction of the portrait of Churchill painted by Graham Sutherland. The picture, a gift from both Houses of Parliament on Churchill's 80th birthday in 1954, was loathed by both Churchill and Lady Churchill and had been stored in the cellars at Chartwell before being burnt in secret. The opening of the house required the construction of facilities for visitors and a restaurant was designed by Philip Jebb, and built to the north of the house, along with a shop and ticket office. Alterations have also been made to the gardens, for ease of access and of maintenance. The Great Storm of 1987 caused considerable damage, with twenty-three trees being blown down in the gardens. Greater destruction occurred in the woodland surrounding the house, which lost over seventy percent of its trees. Chartwell has become among the National Trust's most popular properties; in 2016, the fiftieth anniversary of its opening, 232,000 people visited the house. In that year the Trust launched the Churchill's Chartwell Appeal, to raise £7.1M for the purchase of hundreds of personal items held at Chartwell on loan from the Churchill family. The items available to the Trust include Churchill's Nobel Prize in Literature awarded to him in 1953. The citation for the award reads, "for his mastery of historical and biographical description as well as for brilliant oratory in defending exalted human values". The medal is displayed in the museum room
