Cass County Museum Announces New Building Plans


Cass County Historical Society has started a drive to raise funds for an addition to its building at 646 Main Street in Plattsmouth. The farm building and shed in the museum courtyard are in poor condition and will be demolished. A new 10,000-square-foot building will be constructed to house exhibitions and climate-controlled storage. There will also be renovations to the main building. You can read more about this project by clicking the link above.




Donations for the new building project should be made payable to the Cass County Historical Society Foundation and mailed to 646 Main Street, Plattsmouth, NE 68048.

Cass County Historical Society Museum at 646 Main in Plattsmouth, Nebraska, tells the history of Cass County since 1854, the year the county was opened for settlement. Permanent displays depict various stages in the county's history and are supplemented by temporary exhibits which are changed periodically throughout the year. Visitors learn about the golden age of steamboating on the Missouri River, the pioneer experience, the arrival of the train, and the importance of farm production. A second part of the permanent display covers the age of the automobile, the telephone and radio, churches and religious life, schools, and entertainment. There is a Pioneer room, a Victorian Parlor, and a General Store. The Society also maintains the Joseph and Mary Cook Log Cabin (1868); a Burlington Northern Caboose (1913); a life-size replica of Lewis and Clark's Pirogue which sit at Second and Main in Plattsmouth; and a one-room schoolhouse - Rock Bluffs - which is located southeast of Plattsmouth.
