San Francisco

San Francisco, Spanish for 'Saint Francis', takes its name from Mission San Francisco de Asís, which had been named in honor of Saint Francis of Assisi. The mission received its name in 1776, when it was founded by the Spanish under the leadership of Padre Francisco Palóu. The city has officially been known as San Francisco since 1847, when Washington Allon Bartlett, then serving as the city's alcalde, renamed it from Yerba Buena ('good herb' in Spanish), which had been the name of the first civilian pueblo in San Francisco. Earlier in San Francisco's history, the uninhabited area on the northeastern side of San Francisco was called El Paraje de Yerba Buena, after the herb that was growing abundantly there. The name Yerba Buena continues to be used in locations in the city, such as on Yerba Buena Island. …

The earliest archeological evidence of human habitation in the area dates to 3000 BCE. The Ohlone name for San Francisco was Ahwaste, meaning "place at the bay". The Yelamu group of the Ramaytush people lived in a few small villages when an overland Spanish exploration party arrived on November 2, 1769, the first documented European visit to San Francisco Bay. The arrival of Spanish colonists, and the establishment of the Mission system, marked the beginning of the assimilation of the Ramaytush people and the decline of their language and culture. The Spanish Empire claimed San Francisco as part of Las Californias, a province of the Viceroyalty of New Spain. The Spanish first arrived in what is now San Francisco on November 2, 1769, when the Portolá expedition, led by Don Gaspar de Portolá and Juan Crespí, arrived at San Francisco Bay. …

San Francisco is located on the West Coast of the United States, at the north end of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries. Several picturesque islands—Alcatraz, Treasure Island and the adjacent Yerba Buena Island, and small portions of Alameda Island, Red Rock Island, and Angel Island—are part of the city. Also included are the uninhabited Farallon Islands, 27 miles (43 km) offshore in the Pacific Ocean. The mainland within the city limits roughly forms a "seven-by-seven-mile square", a common local colloquialism referring to the city's shape, though its total area, including water, is nearly 232 square miles (600 km2). There are more than 50 hills within the city limits. Some neighborhoods are named after the hill on which they are situated, including Nob Hill, Potrero Hill, and Russian Hill. …
