The United States' largest urban cultural park is also one of the world's most scenic, with a dazzling array of museums, entertainment venues, botanical gardens and architectural landmarks. The world-renowned San Diego Zoo is just one of the many treasures nestled within the verdant expanse of this 1,200-acre (490-hectare) park, set aside as a reserve for public use as early as 1835. The 1915-16 Panama-California Expo and the 1935–36 California Pacific International Expo left behind a wealth of architectural jewels strewn across the park, including the California Building fashioned after the typical design of a Spanish Colonial Church and now home to the San Diego Museum of Us. Sixteen museums, award-winning theaters, an antique carousel, a miniature railroad and the Spanish Village Arts Center come together at Balboa Park to celebrate the cultural diversity of the state and its inspiring natural landscape.
