One of the Bay Area’s newest museums is hidden among the trees on Angel Island State Park. It tells a story of immigration to the Pacific Coast, with particular emphasis on the Asian experience. The Angel Island Immigration Museum opened in January. It is located inside a former U.S. Public Service hospital built over 100 years ago, where Asian patients were segregated from Europeans. The 10,000-square-foot museum is part of the 15-acre Immigration Station, which operated on the island between 1910 to 1940, in the northeast corner of the island.
