In the middle of San Francisco Bay sits Angel Island State Park. Three thousand years ago, the island was a fishing and hunting site for Coastal Miwok Indians. It was later a haven for Spanish explorer Juan Manuel de Ayala, a cattle ranch, and a U.S. Army post. From 1910 to 1940, the island processed hundreds of thousands of immigrants, the majority from China. During World War II, Japanese and German POWs were held on the island, which was also used as a jumping-off point for American soldiers returning from the Pacific. In the '50s and '60s, the island was home to a Nike missile base.
The site offers tours, exhibits, and educational and recreational programs and events, and works in coordination with the Angel Island Immigration Station Foundation, listed above, for educational programs focusing on the immigration history of the island.
