began in 1958. Duke had learned to play the piano at an early age and developed a lifelong appreciation of jazz and befriended jazz musicians. She also liked gospel music and sang in a gospel choir. Duke cultivated an extensive art collection, principally of Islamic and Southeast Asian art. In 2014, sixty objects from her collection (including ceramics, textiles, paintings, tile panels, and full-scale architectural elements) were displayed temporarily at the University of Michigan Museum of Art in the exhibition "Doris Duke's Shangri La: Architecture, Landscape, and Islamic Art", organized by the Doris Duke Foundation for Islamic Art. The collection is on public display at her former home in Honolulu, Hawaii, now the Museum of Islamic Art, Culture, & Design. Homes Duke acquired a number of homes. Her principal residence and official domicile was Duke Farms, her father's 2,700 acre (11 km2) estate in Hillsborough Township, New Jersey. Here she created Duke Gardens, a public indoor botanical display that was among the largest in America. Duke's other residences were private during her lifetime: she spent summer weekends working on her Newport Restoration Foundation projects while staying at Rough Point, the 49-room English manor-style mansion that she inherited in Newport, Rhode Island. Winters were spent at an estate she built in the 1930s and named "Shangri La" in Honolulu, Hawaii; and at "Falcon Lair" in Beverly Hills, California, once the home of Rudolph Valentino. She also maintained two apartments in Manhattan: a nine-room penthouse with a veranda at 475 Park Avenue that was later owned by journalist Cindy Adams; and another apartment near Times Square that she used exclusively as an office for the management of her financial affairs. She purchased her own Boeing 737 jet and redecorated the interior to travel between homes and on her trips to collect art and plants. The plane included a bedroom decorated to resemble a bedroom in a real house. Doris Duke had difficulty remaining in one place, and whenever she arrived somewhere, she had the desire to go somewhere else. Duke was a hands-on homeowner, climbing a ladder to a three-story scaffolding to clean tile murals in the courtyard of Shangri La, and working side by side with her gardeners at Duke Farms. Three of Duke's residences are currently managed by subsidiaries of the Doris Duke Charitable Foundation and allow limited public access. Duke Farms in New Jersey is managed by the Duke
