Next to the Marion County Historical Society building (1969) are several historic buildings and structures that have been brought to the site. Among these are the Pleasant Ridge Schoolhouse of 1874; the late nineteenth-century Valley Church building; the Chicago, Burlington, and Quincy Railroad Station from Donnely; the reconstruction of a nineteenth-century log cabin from a location near Pleasantville; and the Marysville Covered Bridge. The Marysville bridge was originally built 3.5 miles north of Dallas in 1891. In 1926 the bridge was taken apart and reconstructed over South Cedar Creek, south of Marysville. In 1968 it was dismantled and divided in two, with one 40-foot section going to Marion County Park, the other to the park at Pella. The Town truss wood bridge is covered by a single gable roof.
