These Historic Sites in the U.S. Were Once Endangered. Now They’re Thriving

The barracks at Angel Island Immigration Station were already slated for demolition when state park ranger Alexander Weiss made a discovery.

For 30 years, from 1910 to 1940, the scrap of land in the San Francisco Bay had served as the “Ellis Island of the West,” a way station where immigrants crossing the Pacific were processed before setting foot on mainland U.S. soil.

With the Chinese Exclusion Act in full force, arrivals from China could be detained for months, undergoing dehumanizing medical examinations and interrogations before being granted permission to enter the country or deported back home.

Unused since the 1940s, the historic buildings were off limits to the public. Weiss wanted to see the written and engraved messages himself before they were destroyed.

Entering the barracks in 1970, Weiss trained his flashlight on the walls. They were covered in Chinese writing, not just in one room but everywhere, the calligraphy spreading like wildflowers across the dormitories. Most were poems, more than 200 of them altogether, each an expression of the hopes and fears of the Chinese immigrants detained at Angel Island.

As news of the poetry spread, a movement to save the Angel Island Immigration Station took shape. By 1997, the site had secured National Historic Landmark status. Two years later, the National Trust for Historic Preservation placed the still underfunded and languishing site on its annual list of America’s 11 Most…
