The Aragon Ballroom is one of Chicago's grand old music rooms, built in 1926 with an interior meant to feel like a Spanish palace courtyard. Big-band dancers, boxing crowds, disco nights, and rock audiences have all passed through; today it is still a serious concert venue with a theatrical sense of scale.
Come for a show rather than a daytime look. The building's appeal is in the combination of live music, ornate fantasy architecture, and the slightly battered glamour that only a long-working ballroom can have.
