THOMASTON, Maine (AP) A replica of a Revolutionary War-era Maine home could be closed if the nonprofit running it doesn’t raise $150,000 by the middle of next month.

The Knox Museum, dedicated “to honor the life, times and military service of patriot, soldier, founding father and statesman Henry Knox,” says it faces a dire situation after the state told them it will abandon the building known as Montpelier. The Portland Press Herald reports the state holds the rights to the Thomaston replica home.

The nonprofit Friends of Montpelier operates the museum and grounds. The home is a 1929 replica of the original home, which was demolished by a railroad company in 1871.

Peter Ogden, chairman of the museum’s trustees who signed a letter to supporters, did not respond to requests for comment Tuesday.
