Since 1996, Maine Preservation has released the list of Maine’s Most Endangered Historic Places to boost local efforts and focus positive media attention with an aim to preserve threatened places throughout the state.

"Nomination of an endangered place is a chance for Mainers to make their voices heard and to shine a light on the places that matter to their communities," said Maine Preservation, in a news release.

Maine Preservation is now accepting nominations for its 2026 Most Endangered Historic Places list. In the news release, Maine Preservation said that while not exhaustive, previous listings include bridges, mill buildings, churches, clock towers, neighborhoods, and schools.

To be eligible, a nominated property must be:

• Located in Maine. 

• Culturally, historically, and/or architecturally significant and at least 50 years old.

• Substantially threatened; without intervention the continued existence of the place is at risk. 

• Savable; there is potential to eliminate the threat and to rehabilitate and re-use the property. 

• Supported by a local group advocating for the future of the place that can partner with Maine Preservation.

Nominations are due June 5, 2026. To nominate a property for the list, community members should complete the online nomination form: https://forms.gle/nwcuPMku7FcepkNb6.

Maine Preservation staff and its Board of Trustees review nominations for the final selection. The 2026 list will be announced in September.
