Angel Island (California)

Angel Island (Spanish: Isla de los Ángeles) 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 by humans 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.

The Angel Island Immigration Station, on the northeast corner of the island, which has been designated a National Historic Landmark, is where officials detained, inspected, and examined approximately one million immigrants, who primarily came from Asia.
