The World's Largest Round Barn

Though it lacks a broadside, you still can’t miss this mammoth.

The World’s Largest Round Barn resides in Marshfield, and its architecture is a sight to see. Built in 1916, the barn stands 70 feet high and 150 feet in diameter.

The interesting structure is the main attraction of Marshfield’s fairgrounds, especially during the Central Wisconsin State Fair, which annually attracts thousands of people. Designed to hold purebred animals, the barn fulfills its purpose during the fair’s purebred
shows and sales.
