San Diego is a cultural, educational, and medical center. Its many health facilities include large naval and veterans hospitals. It is the seat of the Univ. of California at San Diego with its Scripps Institution of Oceanography, San Diego State Univ., the Univ. of San Diego, Alliant International Univ., and the Salk Institute for Biological Studies. Balboa Park contains an art gallery, several museums (including an aerospace museum), and the enormous San Diego Zoo. Some buildings from the Panama-California International Exposition (1915–16) and the California Pacific International Exposition (1935–36) remain, and there is a spectacular aquatic park.
Also of interest are Cabrillo National Monument and Mission San Diego de Alcalá (restored). Parts of Old Town are now a state historical park. San Diego is home to a professional baseball (the Padres) and football (the Chargers) team. The San Diego Yacht Club, representing the United States, won the America's Cup in 1987, successfully defended it in 1988 and 1992, then lost it in 1995. The city also has an international airport.
