A dozen nineteenth-century structures have been assembled on this three-acre site adjacent to the Bosque River in order to ensure their preservation. Still located on its original site and now forming the entrance to the museum is the house built in 1869 by Colonel J. D. Berry and mason J. J. Wyatt. The one-and-a-half-story cottage, with two rooms on the first floor and two rooms under the steep roof, is built of fieldstones laid flat with irregularly dressed stone quoins. The vergeboards are jigsaw-cut into fleur-de-lis patterns that are arranged to look like icicles. The three-bay porch dates to 1965. Other notable buildings on the museum grounds include the Stephenville Presbyterian Church (1900), constructed by builder and church leader William J. Wilson. The Latin cross plan has a three-stage tower with an octagonal tower and a steeple. The two-story Oxford House (1890s) is an elaborately decorated Queen Anne design with a wraparound porch, multiple gables, and a square tower.
