The Dr. G.C. Stockman House
Architecture and the Prairie School

Mason City is widely known for its collection of Prairie School architecture. The Rock Crest-Rock Glen Historic District is the largest concentration of any city in Iowa. At least 32 houses and one commercial building were built in the Prairie Style between 1908 and 1922, 17 of which are listed on the National Register of Historic Places and eight more are contributing properties to a historic district.[24][25]

The first two Prairie structures, the Dr. G.C. Stockman House (1908) and the Park Inn Hotel and City National Bank Buildings (1909–1910) were both designed by Frank Lloyd Wright. The hotel and bank, a mixed-use development at the corner of State and Federal Avenues was the first to be commissioned by local attorneys James E. E. Markley and James E. Blythe. Within a year, Wright was hired to design the Stockman House by Markley's neighbor.[26]

Both the Park Inn Hotel and Stockman House suffered from neglect and unsympathetic alterations before they were saved by community organizations. In 1989, the Stockman House was moved four blocks to prevent its demolition; it was subsequently restored and opened to the public by the River City Society for Historic Preservation.[27] Likewise, Wright on the Park, Inc. began restoration on the Park Inn Hotel in 2005 and the former City National Bank building in 2007. The organization reopened both buildings as a boutique hotel in August 2011.[28][29] The Park Inn Hotel is last remaining of the few hotels that Wright completed during his career and is considered a prototype for Wright's Imperial Hotel.[30]

The Rock Glen and Rock Crest National Historic district is a small enclave of single-family homes situated along the banks of Willow Creek five blocks east of downtown. It is the largest collection of prairie-style homes in a natural setting in the world.[citation needed] It features both Prairie School and Usonian design.[citation needed] Five of these houses were designed by Walter Burley Griffin and Marion Mahony Griffin, two by Francis Barry Byrne, and others by William Drummond, Einar Broaten, and Curtis Besinger.[citation needed]

In addition to Prairie Style architecture, Mason City is home to extensive Victorian, Craftsman, and Bungalow style homes, as well as historic commercial structures, dates from between 1892 and 1940, including the Brick and Tile Building at the intersection of State and Delaware Streets.

The Mason City Public Library was designed by Chicago architects Holabird and Root in 1939.[31]

The Len Jus Building on North Federal Avenue has an extremely rare sheet-metal facade, it had been placed on the Iowa Historic Preservation Alliance's Most Endangered list because of its poor repair and indifferent ownership,[32][33] but is now being rehabilitated by the new owner.


Mason City has some history of minor league and amateur sports teams despite its relatively small size.

The North Iowa Bulls are a junior ice hockey team that first began play in the 2011 as member of the North American 3 Hockey League (NA3HL).[34] The Bulls won the league championship in 2013, 2014, 2016, and 2021, while also winning the Tier III National Championship in 2013 and 2015. The Bulls moved up to the Tier II North American Hockey League (NAHL) and rebranded the Tier III team as the Mason City Toros in 2021. The North Iowa Outlaws junior hockey team previously played in the NAHL from 2005 until 2010, when they relocated to Onalaska, Wisconsin, to become the Coulee Region Chill. The North Iowa Huskies played in the United States Hockey League from 1983 to 1999 and then moved the Cedar Rapids.

Mason City was home to minor league baseball. The Mason City Cementmakers (1912) and Mason City Claydiggers (1915-1917) played as members of the Iowa State League (1912) and Central Association (1915–1917). The teams played at Hanford Park.[35]

The Mason City Bats of the short-lived Great Central League played baseball here in 1994.[citation needed]

College Football Hall of Fame coach Barry Alvarez led Mason City High School to the 1978 Class 4A state football championship with a 15–13 victory over Dubuque Hempstead.
