In 1936, tobacco heiress Doris Duke and her then husband, James Cromwell, purchased beachfront property just east of Diamond Head. The couple built a lavish home overlooking the sea, and Duke spent the rest of her life filling it with Islamic art; richly colored carpets and embroideries, elaborate tile mosaics, carved wood and marble paneling, and architectural flourishes throughout. The residence is now known as Shangri La: Center for Islamic Arts and Cultures, and special guided tours offer you the opportunity to step inside a house that's less a home and more a living piece of art in its own right. The tour takes you through the house and around the grounds, allowing you to marvel at the detailed work inside, and the spectacular ocean views outside. It's one of the most unique tours available on Oahu.How to get to the Shangri LaTours of Shangri La are only available via shuttle from the Honolulu Museum of Art; no walk up visitors are allowed.
