Antioch, CA is the 2nd largest city in Conta Costa County. Located in the East Bay region of the San Francisco Bay area, the city is located near the San Joaquin-Sacramento River Delta.

Incorporated on February 6, 1872, Antioch is one of the oldest towns in CA. Founded in 1850 by brothers William & Joseph Smith, they named the city Smith’s Landing after themselves. The following year, their new minister persuaded them that the biblical name of Antioch would be more fitting. They obviously consented.

As was common among early cities, the first business enterprises were agriculture and farming. In 1859, coal deposits were discovered and broadened the economy. Several years later, copper was discovered and several smelting operations were built.

Antioch today is famous for its mild year round climate, beautiful geography, and a mixture of arts and culture. The Prewett Family Water Park affords a fun family outing for all to enjoy. The city itself touts the affordability of both residential property and commercial property- believing itself to be the most affordable city in the bay area.
