The enormous Umaid Bhawan Palace has the distinction of having been one of the largest private residences in the world. It has 347 rooms and used over 2.5 million cubic feet of sandstone and marble. It is a splendid example of Indo-colonial and art deco architecture of the 1930s. The interior of the palace was decorated in the Beaux Arts and Art Deco styles. And it incorporated everything from two theaters and an indoor swimming pool to its own central air-cooling plant. A portion of the palace has been converted into a hotel, the other remains on view to visitors in the form of an excellent museum which houses model airplanes, weapons, antique clocks, priceless crockery and hunting trophies. Both sections retain the ambience of royal splendor.
