The handsome brick and stone structure, listed on the National Register of Historic Places, was completed in 1845. Exhibits feature Native American artifacts including a dugout canoe; displays on ice harvesting, steamboats and hotels; local memorabilia and historical maps, books and prints. A light-up map shows historic sites around the lake.
