Cass County Historical Society Museum tells the history of Cass County since it was opened for settlement in 1854. Exhibits are changed quarterly to highlight difference aspects of the collection. The historical society also maintains the Joseph and Mary Log cabin built in 1868, a Burlington Northern Caboose, and a replica of Lewis and Clark's Pirogue located in a park at Second Main in Plattsmouth and Rock Bluffs School, a one room brick school house, located 10 miles south of Plattsmouth. The museum is open Tuesday through Saturday from 12:00 to 4:00 p.m. The log cabin, caboose, pirogue and school are open for special occasions or by appointment.
