SAN FRANCISCO, May 20, 2026 /PRNewswire/ -- The National Trust for Historic Preservation has named the Angel Island Immigration Station to the 2026 list of America's Most Endangered Historic Places for a second time.

After the site was previously included on the list in 1999, Angel Island State Park and the Angel Island Immigration Station Foundation made significant progress to restore the detention barracks and hospital building. Despite these successes, however, the site continues to face significant endangerment due to a unique combination of physical, environmental, and economic factors.

Today, the site still requires financial investment to protect and maintain Angel Island's historic buildings, continue and expand public-facing programs, raise public awareness, and improve access for visitors. The story of Angel Island is necessary in conveying the full American narrative about how the principle, All People Are Created Equal, was systematically denied for many, including Asian and Pacific Island immigrants, and how their pursuit of the principle required resilience and perseverance in times of injustice.

Carol Quillen, President and CEO of the National Trust for Historic Preservation stated, "The Angel Island Immigration Station tells the story of thousands of immigrants, many from Asia and across the Pacific, and their resilience in the face of lengthy interrogations and detentions, invasive medical exams, and family separation. The site is crucial in understanding America's immigration history, and serves as a visceral reminder that our country, 250 years later, is still on the journey to achieving its vision of true equality."

From 1910 to 1940, over one million persons from 80 different countries were processed or detained at the former U.S. Immigration Station at Angel Island. While sometimes referred to as the "Ellis Island of the West," Angel Island's immigration station functioned as an immigrant detention center that was built to enforce the Chinese Exclusion Act of 1882 and similar policies that sought to keep Asian and Pacific Islander immigrants from entering the nation.

"California State Parks deeply appreciates the recognition and visibility that the National Trust for Historic Preservation's inclusion on the list provides for the Angel Island Immigration Station," shared Bay Area District Superintendent Maria Mowrey.

Edward Tepporn, Executive Director of the Angel Island Immigration Station Foundation noted, "For over 43 years, AIISF has worked in close partnership with Angel Island State Park to preserve the buildings at the site and the histories of its immigrants. Yet, despite these efforts, the majority of people in the U.S. still do not know about Angel Island and its historic significance. As America celebrates its 250^th birthday, we encourage everyone to remember, reflect upon, and learn from all of the events in our nation's history; the times when the U.S. has shined the brightest in our accomplishments and ideals as well as the times when we have fallen short of our values in our actions."
