Benton of Southern California, hired by town founder Thomas W. Patterson. It is the oldest building in Patterson and the center of the planned town. It also housed the ranch company offices, irrigated farm sales offices, the post office and a bank.","narrative":"Built between 1909 and 1910 on a circular plot at the center of Patterson, California, this small Mission Revival building anchors a town laid out by Thomas W. Patterson with eight streets radiating from a central circle. Its wood frame sits on a concrete foundation, with stucco walls, a flat roof, small wings at each end, arched windows and two entry porches. Southern California architect Arthur B. Benton designed it, along with the town's first hotel and mercantile building, and local architects supervised construction. Contractor F.W. Maurice finished the work on October 14, 1910. In its early years it held the ranch company offices, the irrigated farm sales offices, a bank and the post office, which operated there from 1910 to 1931. It is the oldest building in Patterson. The city has owned and maintained it since the early 1940s, and it now houses a historical society museum and the Chamber of Commerce.","period_of_significance":"1910","architect_builder":"Benton, Arthur B.
