The diverse history of San Francisco did not start in with the California Gold Rush in the 1840s. Nor did it begin in 1776 when the Spanish established a Mission and a Presidio. Instead, San Francisco’s history dates back thousands of years further in time. During those millennia California was the land of Native Americans, and the Ohlone Tribe called San Francisco, and indeed much of the Bay Area home, as do their descents today. Yet, standing at the Moscone Center in the heart of this urban setting, it may seem an impossible task to envision what everyday life was like on this spot 500 or 1000 years ago.
