The Thomaston Historical Society operates its library and museum from the last surviving building of the original Knox estate. General Henry Knox, a Revolutionary War veteran and the first Secretary of War under President George Washington, built his estate between 1795 and 1797. He moved to the area after retiring as the Secretary of War so that he could spend more time with his family. It consisted of his mansion, the farmhouse and several outbuildings constructed on the land. The farmhouse (the home of the historical society) was the only building left standing when the railroad was laid through the property in the 1870s. It was listed on the National Register of Historic Places in 1974 as part of the Thomaston Historic District.

General Henry Knox built the farmhouse and several other buildings when he retired to this estate, which he called “Montpelier,” after years of service in the Revolutionary forces at the command of General George Washington. When Washington became President of the United States, he appointed Knox as his first Secretary of War. Knox retired in 1796 to attend to his growing family. He moved them to Thomaston, Maine and built this estate. The only building still standing from the original group of structures is the one that houses the Thomaston Historical Society. It used to be his farmhouse – a home for the tenant farmers and other workers on the property. After the last family member died in 1854, the property had stood abandoned for several years. Knox’s beautiful mansion was razed in 1871 to make way for the new railroad. The farmhouse was converted into Thomaston’s railroad station.  It was renovated to have ticket windows in the front so that people didn’t have to go inside to purchase their tickets. A covered platform was constructed near the rails. Now, the train still passes close by the museum a couple times a day. It’s loud and causes the building to tremble a bit.

Eventually the railroad station was abandoned. The property was turned over to the local chapter of the Daughters of the American Revolution (DAR). The Thomaston Historical Society was formed in 1972. At that point, the DAR decided that the historical society would be able to use the building and transferred ownership to it. The building underwent an extension renovation in the 1970s before it opened as a public museum.

Several buildings in Thomaston, Maine were included in the National Register of Historic Places Inventory Nomination Form as the “Thomaston Historic District.” The District is made up of several 19th century buildings, mostly Federal and Greek Revival architectural style homes and some businesses, that run along a two-mile stretch of Route 1 through Thomaston. The museum’s building is listed as the Thomaston Railroad Station.  The form notes that it is the “surviving building from the estate of General Henry Knox, which was originally located on this site at the foot of Knox Street. Built in 1795, it was originally the cookhouse.”

The museum is open during the summer, on Tuesdays, Wednesdays, and Thursdays from 2 PM to 4 PM and on Saturdays from 1 PM to 3 PM. Admission to the museum is always free and there is someone from the historical society there to give a tour or answer questions. It is also open by appointment only through the rest of the year.
