The museum maintains a library of historical and genealogical texts for use by researchers.

Works of local artists are hosted in the second floor art gallery. The exhibits are changed on a bimonthly basis. The museum's collectibles includes works or prints by well known artists with local ties, such as Lewis Miller and Walter Biggs.

The building housing the museum was originally built circa 1852 as the Manse for the Christiansburg Presbyterian Church. The Rev. Nicholas Chevalier was one of the first occupants of the home. The construction of the original portion is an interesting combination of American and Flemish bond brick. According to oral tradition, the bricks were made on the property and fired in an earthen kiln. Support beams and joists are of hewn oak. The rafters are of logs planed on one side and secured by dowel pins.
