The Stoughton Main Street Commercial Historic District is a collection of 36 surviving historic business structures in the old downtown of Stoughton, Wisconsin, United States.

The Milwaukee and Mississippi Railroad reached town in 1853, making Stoughton a shipping center for wheat from the surrounding farms.

Mandt started a wagon-making factory the 1860s which was so successful that the town was known as "the Hub City."

In 1880 Mandt's factory produced 5,000 wagons, 50,000 to 75,000 wheel hubs, and employed almost 200 men.

The owners and city decided to rebuild the entire block in brick, two stories tall, with a unified design.
