San Francisco, was founded in June of 1776 by Spanish colonists. Named after St. Francis of Assisi, the city was already well established when the gold rush of 1849 brought such an influx of residents and businesses that it became the largest city on the entire West Coast of California.

Prior to the earthquake of 1906, one in every four residents of California resided in San Francisco. During World War II, the port of San Francisco was the hub for sending all US military to the Pacific Theater. The United Nations was started here in 1945 at the end of WWII.

Famous for hosting the Hippie counter culture of the 1960’s, it later became the heart of the movement to recognize gay rights. A notably liberal city, San Francisco remains the heart and soul for individual causes.

Sites like Alcatraz, the Golden Gate Bridge, Chinatown and the famous cable cars attract tourists from all over the world. Fisherman’s wharf and the other world class restaurants of San Francisco make sure none of the tourists have far to go to find the best food this wonderful city has to offer.
