Angel Island State Park

Angel Island is an island in San Francisco Bay. The entire island is included within Angel Island State Park, administered by California State Parks. The island, a California Historical Landmark, has been used for a variety of purposes, including seasonal hunting and gathering by Indigenous peoples, water and timber supply for European ships, ranching by Mexicans, United States military installations, a United States Public Health Service Quarantine Station, and a U.S. Bureau of Immigration inspection and detention facility. It has been compared to Ellis Island in New York, both being centers of immigration.
