Learn about each of the sites on the 2025 Most Endangered Historic Places in Illinois. Since 1995, Landmarks Illinois has published an annual list of the state’s top threatened culturally and architecturally significant sites threatened by deterioration, lack of maintenance, insufficient funds or inappropriate development. Learn more about the annual program here.
“This year’s Most Endangered list is wide-ranging, not only in the kinds of troubling threats these places face, but also in their historical narratives, geographical locations and building types. Yet all celebrate cultural heritage and tell the important stories of the people who have shaped our communities. Landmarks Illinois feels a heightened responsibility this year to speak out and protect the built environment that reflects the rich diversity of our state and nation. As these irreplaceable sites face being erased, we remain steadfast in our commitment to preserve and honor our past, knowing that our history has the power to shape a more inclusive future.”
The immense campus, built between 1938 and 1941 in Chicago’s Avalon Park neighborhood, is home to the city’s largest non-skyscraper example of Art Deco design. The school’s “Anthony Wing,” which formerly housed the heavy industry vocational programs, sits empty while the rest of the Chicago Public School-owned building is significantly underutilized in light of dwindling enrollment.

The historic opera house, built in 1884, is located prominently on Watseka’s Main Street and was once a community hub for the arts and retail business. The City of Watseka purchased the vacant and deteriorating building in 2023. However, deferred maintenance has made restoration difficult and expensive. As a result, the city has discussed demolishing it for use as a parking lot or selling the building.

Illinois is home to a handful of architecturally significant, federally owned buildings managed by the General Services Administration. Among these are three Modernist buildings the federal government has previously identified as wanting to sell: the U.S. Post Office and the Kluczynski Federal Building in Chicago, the Senator Paul Simon Federal Building in Carbondale, and the East St. Louis Federal Building. All three lack local landmark designation that would protect them against demolition or inappropriate redevelopment if sold to private developers.
Considering the rapid changes occurring under the Trump Administration, we feel it is imperative to monitor potential threats to these and other Illinois federally owned buildings that stand as prominent community markers and play key roles in civic and economic life.
