The Mercer County Historical Society, in Aledo, Illinois, was formed in 1955 and opened to the public in 1959. It is named for the parents of E.L. Essley, who donated the funds to build the museum. Here at the museum we also have a one-room schoolhouse. Thousands of artifacts are on display at the museum from years gone by. Many of our artifacts and machinery are from the 1800's.

We offer a wealth of amazing research opportunities for historians and individuals interested in genealogy and learning more about the past.
