Although the majority of Hillside's later construction was located north of 12th Street, Immanuel Lutheran Church and School were incorporated inside village boundaries, giving Hillside its characteristic form. However, Marion Covell found a significant limestone deposit just a few feet below the surface of his property during the 1850s, despite the fact that farming was the main industry at the time. The quarry he started in 1854 was still in operation until the middle of the 1970s, providing crushed stone for the construction of roads across the Chicago metropolitan area. The John Sexton Company purchased the quarry in 1979 and operated it as a sanitary landfill. Cemeteries also took the place of active farming immediately beyond Hillside on its western and southern borders, first with Mt. Carmel in 1894, then Oak Ridge, Glen Oak, and ultimately Queen of Heaven in 1947.Addison is a village located in the Chicago Metropolitan Area, in DuPage County, Illinois, United States.
