The DIA holds one of the world's finest art collections. The centerpiece is Diego Rivera's mural Detroit Industry, which fills an entire room and reflects the city's blue-collar labor history. Beyond it are Picassos, Caravaggios, suits of armor, modern African American paintings, puppets and troves more spread through 100-plus galleries.

　　It's hard to believe the museum's collection was about to be sold to pay off the city's debt back in 2013. Luckily, donors saved the day.
