Famous for its beautiful setting, San Francisco is built on a series of steep hills located on the northern tip of a peninsula at the entrance to San Francisco Bay. The bay and its extensions, which include San Pablo Bay and Suisun Bay, constitute one of the great natural harbors of the world, embracing nearly 1,200 sq km (more than 450 sq mi) of water. Because of this, San Francisco was once the major Pacific Coast seaport of the United States. Today the city is an important center for finance, technology, tourism, and culture. The city was named after San Francisco Bay, which in turn was named for Saint Francis of Assisi by early Spanish explorers.
The people of San Francisco can take pride in their city's accomplishments. San Franciscans, and in some cases their counterparts in the Bay Area, have successfully undertaken mammoth construction projects such as the San Francisco-Oakland Bay Bridge, the Golden Gate Bridge, and the Bay Area Rapid Transit system. Since at least the 1950s, San Franciscans have also earned a reputation for tolerance of and respect for diversity.
