Located on a mountain overlooking the sea, there is a very special museum on the coast in central California: Hearst Castle. The origins of that property go back to 1919, when William Randolph Hearst hired the architect Julia Morgan to build his home on a plot of about 25,000 acres. The construction took almost 20 years and includes guest houses with a total of 46 rooms, an outdoor pool (Neptune) and an indoor pool (Roman). Gardens and works of art surround the main building, known as the Casa Grande, with a total of 115 rooms including a refectory, billiard room, theater, library, Gothic studio, beauty salon, kitchen and the staff dining room. This castle is one of the hidden treasures found near the Pacific coast. This magnificent work of architecture, which became part of the list of United States National Historic Landmarks on May 11, 1976, is worth the trip.
