Maine Preservation, a statewide historic preservation organization, announced today 11 pieces of the state's heritage that are threatened by neglect, or in some cases, progress.

The group's list includes buildings that could fall into disrepair, but also includes less obvious pieces of the state's cultural heritage. The list was announced at a news conference held at Pennell Institute and Campus in Gray, a former school building that preservationists want to save.

Included in the list are not only the buildings of Maine's working waterfront, but also the nature of the work done there.

The list includes old municipal tax lists, often the only record of when properties were built or when the first radio was purchased by a town resident.

The group this year adopted a theme of environmental stewardship -- promoting the energy savings that can be realized by preserving existing structures rather than building new. Every 50 square feet of brick wall represents 700 gallons of gasoline to make, erect and haul away as debris, said Maine Preservation executive director Greg Paxton.

Historic houses of worship like the Free Will Baptist Church in Bowdoinham and United Baptist Church in Lewiston are on the list, as well as the Masonic Temple in Portland.
