|About the County Historical Museum and Archival Library
|The Museum and Archival Library buildings and collections belong to the Madison County Historical Society. Through a lease agreement, Madison County provides funding to help make the collections available to the public. The Museum Department staff report to the Madison County Board.
The Museum is housed in the 1836 Weir House. Designated in 1985 as a National Historic Place, the house is the second oldest brick home in Edwardsville.
