The Livadia Palace was a summer retreat of the last Russian tsar, Nicholas II, and his family. The Yalta Conference was held there in 1945, when the palace housed the apartments of Franklin D. Roosevelt and other members of the American delegation. Today the palace houses a museum, but it is sometimes used by the Ukrainian authorities for international summits. It is built of white Crimean granite in the Neo-Renaissance style. It contains 116 rooms with interiors furnished in different styles. There is a Pompeian vestibule, an English billiard-room, a neo-Baroque dining room, and a Jacobian-style study of maple wood, which elicited the particular admiration of Nicholas II.
