This iconic landmark is a welcome center for visitors and Chicago residents alike. Once the central public library, it shifted to a public arts and events center in 1977. In addition to offering a rich variety of cultural events year-round, it’s stocked with maps, rest areas, and wifi——all free of charge! The best way to explore is to walk around the building: take the stairs and take it all in. There’s two stained glass domes and special exhibitions spaces throughout the building.
