Since 1995, Landmarks Illinois has asked preservationists, community leaders and concerned citizens throughout the state to nominate threatened or endangered historic properties for its annual list, the Most Endangered Historic Places in Illinois. The purpose of the list is to focus attention on sites threatened by deterioration, lack of maintenance, insufficient funds or inappropriate development and to bolster local advocacy efforts and build support for each property’s eventual preservation. The Most Endangered Historic Places in Illinois list also draws attention to important policy issues that affect these properties and historic properties throughout the state.
Once a property is included on the Most Endangered list, Landmarks Illinois remains committed to its preservation efforts, continuing communication and relationships with local advocates and elected officials to provide resources (including small grants) and connections where possible. In many cases, this has led to years- or decades-long relationships between local advocates and Landmarks Illinois. Staff at Landmarks Illinois can also serve as a link to pro bono services from other preservation professionals such as architects, engineers, historians and more.
Landmarks Illinois has announced the 2025 Most Endangered Historic Places in Illinois. The list calls attention to 10 culturally and architecturally significant sites across the state that face growing threats of disinvestment and demolition. For the first time, it also includes a “Watch Site.” Click below to explore the places on this year’s list.
