The Mead Building was constructed in 1909 under the direction of Dr. Leonard C. Mead. It was originally part of the women’s ward for the Dakota Hospital for the Insane, now named the Human Services Center.  It was a grand facility utilized until the 1980’s. 

In 2008 the Yankton County Historical Society voted in favor of saving and rehabilitating the building for use as a museum and education center. It opened to the public in December of 2018. 

The MCEC feature exhibits on local and region history, details

on those exhibits can be found in the Exhibitions tab.

Our Story 

1936 to Present

In June, 1936 Yanktons first museum opened under the direction of the Daniel Newcomb Chapter of Daughters of the American Revolution. The Museum was located in the former Dakota Territorial Council Hall - which had been relocated in present-day Riverside Park.

In 1953, the hall and museum were moved to West Side Park.

In 1961 the Yankton County Historical Society was officially formed and took over care of the Museum.

The 1971 a new and larger building was built next to the old council building. For more than 30 years the Museum has called this building home. The former Dakota Territorial Council building remained as extra exhibit space, and many additional outside buildings have been added, including the Gunderson Rural School House, Hovden Cabin and the Burlington Northern Caboose. 



2012, the YCHS Board of Directors accepted the task of saving a building located on the north edge of Yankton that was part of the former Dakota Hospital for the Insane campus.


The Mead Building has been a multi-year, multi-million dollar venture that reopened in 2018 as the Mead Cultural Education Center (MCEC). The MCEC is home to the Yankton County Historical Society, Dakota Territorial Museum, and the future home of the Yankton College Alumni offices. Our new location is 82 Mickelson Drive in Yankton South Dakota.

And even though we are open, the task of restoring the Mead building is not complete! The first two floors have completed exhibits and traveling exhibits space. The basement, third floor, and east wing are still in the construction phase. We are also fundraising for Heritage Park and planning to move all our historic buildings in 2021.
