"Locke, also known as Locke Historic District, is an unincorporated community in California's Sacramento – San Joaquin River Delta built by Chinese immigrants during the early 20th century. It was originally named Lockeport after George Locke, a local land owner. It is located in the primarily agricultural region south of Sacramento, California, near State Route 160. It was listed on the National Register of Historic Places in 1971 and further was designated a National Historic Landmark District in 1990 due to its unique example of a historic Chinese American rural community."
