Thompson's Block

Thompson's Block is a historic building at 119 E. Main Street in Madison, Wisconsin. It was built in 1868 as a grocery store for businessman Ole Thompson; at the time, it was one of twelve grocery stores on Main and King Streets. The three-story brick building has an Italianate design with a cast iron storefront, segmental arched windows on the upper stories, and a dentillated cornice. The building was used as a grocery store until the 1930s, when it was converted to a bar with offices on the upper stories. It is one of the few surviving buildings from Madison's original downtown commercial district.

The building was listed on the National Register of Historic Places in 1984 and on the State Register of Historic Places in 1989.
