The Utica Museum Complex houses the LaSalle County Historical Society, a group that acquired the stone warehouse (ca. 1848), one of 3 remaining original buildings on the I&M, which houses the society’s headquarters as well as a bookstore/gift shop and a number of exceptional exhibits. Also part of the complex are the Aitken School, an 1865 one-room school house, a stone blacksmith shop (ca. 1892) which houses a fine blacksmith tool collection, and an original white pine pegged barn (ca. 1875) with antique tool collection.
