New York and Washington D.C. may have more cultural institutions per square mile but Detroit has plenty to offer any visitor looking for something that's not food-, drink-, or sports-related. Start the day at the Detroit Institute of Arts, a world-class museum that almost had to sell its paintings a few years back. Luckily, you can still enjoy your Rembrandts and Rodins in peace. Take in a play or an opera or learn about the stars. You'll need more than a day to see the cultural sites here.
