Chicago has always seemed like a magical place, one where past and present intertwine. It’s a haunted city, animated by memory, that often feels unmoved by the passage of time. Nowhere is this more strongly felt than in the architecture, buildings in which the spirits of Sullivan, Burnham, and Wright persist. But even in lesser-known structures, the smaller buildings populating neighborhoods throughout the city, ghosts remain. The tops of these structures, with their intricate tile work and ornate stone facades, offer glimpses of the past. To keep your eyes lifted is to be transported back in time, to imagine all the wondrous things those buildings may once have held. But to drop your eyes is to be confronted by the present—a discount shoe store, a carry-out restaurant—some quotidian thing that makes all the ghosts disappear.
