The Two Brothers Roundhouse, formerly the Walter Payton Roundhouse, America's Historical Roundhouse, and Chicago, Burlington, & Quincy Roundhouse and Locomotive Shop is a historic building converted to a restaurant in Aurora, Illinois. It was originally constructed in 1856 as a roundhouse for the Chicago & Aurora Railroad (later Chicago, Burlington & Quincy Railroad) and served in this capacity until 1974. It was abandoned until 1995, when a group of investors led by Walter Payton purchased it and converted the building to an entertainment complex. Its most recent tenant is Two Brothers Brewing. The building is the oldest limestone roundhouse in the United States and is listed on the National Register of Historic Places.
