San Francisco is a major city in California, the centerpiece of the Bay Area, well-known for its liberal community, hilly terrain, Victorian architecture, scenic beauty, summer fog, and great ethnic and cultural diversity. These are only a few of the aspects of the city that make San Francisco one of the most visited cities in the world.
Prior to European settlement in the area, the peninsula that now contains San Francisco was home to the Yelamu tribe, who were part of the larger Ohlone language group which stretched south from the Bay Area to the Big Sur of California. Due to San Francisco's characteristic foggy weather, the earliest European explorers completely bypassed the Golden Gate and the San Francisco Bay. The first European settlement in the area was founded by the Spanish in 1776 as a mission community surrounding the Mission San Francisco de Asís, in what is today called the Mission Dolores in the Mission District. In addition to the mission, a military fort was built near the Golden Gate: El Presidio. Upon gaining independence from Spain in 1821, the area became part of Mexico. Under Mexican rule, the mission system gradually came to an end and private ownership of land became a possibility. In 1835, an Englishman named William Richardson founded the town of Yerba Buena, the first significant settlement on the peninsula outside of the Mission Dolores area. As the new settlement gradually grew, Yerba Buena developed a street plan and became attractive to settlers.
