Hearst Castle rises above California's coast at San Simeon, but its essential story begins with a ranch and a conversation. George Hearst acquired land here in 1865. His son, publisher William Randolph Hearst, inherited property around San Simeon in 1919 and asked architect Julia Morgan to develop a retreat on the hill. The collaboration lasted nearly three decades. What began as an informal camp became La Cuesta Encantada, the Enchanted Hill, an estate that combined grand rooms, guesthouses, gardens and a far-ranging art collection. It remained unfinished when Hearst left in 1947 because of poor health. That unfinished quality is part of the place, not a flaw to conceal.
California State Parks now operates the property as Hearst San Simeon State Historical Monument. Its account describes a main house, Casa Grande, with 115 rooms, three guesthouses and two pools. The wider estate has 165 rooms. Numbers can suggest excess, but the more interesting question is how Hearst and Morgan worked together. Hearst brought tastes formed by travel and collecting; Morgan translated changing wishes into a difficult hilltop construction project. She was an architect with her own vision and technical authority, not an anonymous assistant to a wealthy client.
