WASHINGTON, D.C. — The National Trust for Historic Preservation on Wednesday, May 20, 2026, released its annual list of the 11 most endangered historic places in the United States, with the 2026 edition tied to the nation's 250th anniversary and the principle that all people are created equal. Each site on the list will receive a one-time grant of $25,000 from the organization, which has issued the list every year since 1988.

"We chose to focus this year on sites important to the idea that all people are created equal," said Carol Quillen, president and CEO of the National Trust for Historic Preservation. "Over time, brave people have fought for equality before the law, equal opportunity, freedom of speech, due process, birthright citizenship."

The 2026 list focuses on equality and erasure. "One of the ways that you can lose a site is through erasure, [when] what happened there is gradually forgotten or intentionally erased. And so that's a form of a threat to preservation that we're also interested in protesting," she said.

The named sites include the Ben Moore Hotel in Montgomery, Alabama; the Tule Lake Segregation Center in Modoc County, California; Angel Island Immigration Station in Tiburon, California; Swansea Friends Meeting House in Somerset, Massachusetts; the Detroit Association of Women's Clubs in Detroit; the Greater Chaco Cultural Landscape spanning New Mexico, Colorado, Arizona and Utah; Women's Rights National Historical Park in Seneca Falls, New York; Stonewall National Monument in New York City; the President's House Site in Philadelphia; and El Corazon Church in Texas. The Swansea Friends Meeting House was established in 1701 by the Society of Friends fleeing religious persecution and is structurally damaged and requires repairs. The Detroit Association of Women's Clubs, founded in 1921, has been closed since 2024 because of damage from a burst water pipe.

The Ben Moore Hotel, long vacant and suffering from structural deterioration, was listed in the Green Book that directed Black travelers during the Jim Crow era. The Conservation Fund said in November that it would help preserve the building. Much of the 1,100-acre Tule Lake Segregation Center site is threatened by a proposed airfield fence. Several detention barracks at Angel Island Immigration Station have been restored, but the site remains threatened by physical, environmental, political, and economic factors. The Greater Chaco Cultural Landscape, a sacred ancestral homeland of Pueblo and Hopi people and one of only 20 World Heritage properties in the United States, is threatened by proposed oil and gas development on federal land surrounding Chaco Culture National Park.

The Pride flag at Stonewall National Monument was removed by the National Park Service in February, with the agency citing federal guidance that limited flag displays. The Trump administration reversed course in April and agreed to restore the flag after settling a lawsuit filed by advocacy and historic preservation groups.
