Museum of Science & Industry
Spread across roughly 14 acres, Chicago's Museum of Science & Industry is one of the world’s largest museums, with more than 35,000 artifacts displayed in 2,000-plus interactive exhibits. Designed in 1892, the museum’s Classic Revival structure was first built to house the Palace of Fine Arts for the World’s Columbian Exposition. Today, the structure is home to a simulated coal mine, a fairy castle filled with real diamond chandeliers, the world’s largest pinball machine, and the only German U-boat in the country. Visitors can also watch baby chicks hatch before catching a show in the five-story, domed Omnimax Theater.
