Excerpt from Wikipedia:

“Construction was completed in 1926. The Aragon was designed in the Moorish architectural style, with the interior resembling a Spanish village. Named for an autonomous community of Spain, the Aragon was an immediate success and remained a popular Chicago attraction throughout the 1940s. The Aragon’s proximity to the Chicago ‘L’ (elevated railway) train provided patrons with easy access, and often crowds in excess of 18,000 would attend during each six-day business week. Each night, powerhouse radio station WGN broadcast an hour-long program from the hall to audiences throughout the Midwestern United States and Canada.”

“The ceiling looked like the sky, the clouds moved across the stars.”

Tom Cartmell writes that he wishes he were with Elaine and Stanley when they went to the Aragon Ballroom in August of 1943.
