The city limits of Los Angeles bordering its western edge.The San Gabriel valley derives its name from the San Gabriel River that flows southward through the center of the valley, which itself was named for the Spanish Mission San Gabriel Arcángel originally built in the Whittier Narrows in 1771. At one time predominantly agricultural, the San Gabriel Valley is today almost entirely urbanized and is an integral part of the Greater Los Angeles metropolitan area. It is one of the most ethnically diverse regions in the country. About 200 square miles (520 km2) in size, the valley includes thirty-one cities and five unincorporated communities.
