When the Madison County Historical Society was organized in 1928, their main objective was to collect, preserve and display history and memorabilia to recount Madison County history.
In May 1966, to usher in the Centennial of Nebraska and the city of Madison in 1967, the Historical Society opened the County Museum above the old City Hall. In 1998, the City of Madison built the present modern facility to house the County Museum, City Library, and City Office.
The former Carnegie Library building is now home
to the Carnegie Learning Center where special events for students are
held.
The Learning Center has an old time school
setting, an activity barn with animal puppets; a costume theater area;
the Cat in the Hat reading area; and other rotating children's
activities.
