Welcome to the largest historic public market district in the United States. You'll eat, you'll shop, take some photos, and go home happy and take a well-deserved nap. Start this tour before 9AM if you want the best selection of stuff, or start later for the best selection of people-watching.
The locations, descriptions, and pictures in this tour are taken from Wikipedia: http://en.wikipedia.org/wiki/National_Register_of_Historic_Places_listings_in_Detroit,_Michigan . "This is a list of the National Register of Historic Places listings in Detroit, Michigan. It is intended to be a complete list of the properties and districts on the National Register of Historic Places located in Detroit, Michigan, United States but outside of the Downtown Detroit and Midtown Detroit neighborhoods."
This tour is copy-and-pasted from NY Mag's Detroit Tour suggestions: http://nymag.com/travel/weekends/detroit/index4.html . And I quote: "Take a break from food tourism and spend a day checking out the city’s renegade public-art scene."
