Mason City is a city and the county seat of Cerro Gordo County, Iowa, United States. The population was 27,338 in the 2020 census, a decline from 29,172 in the 2000 census. The Mason City Micropolitan Statistical Area includes all of Cerro Gordo and Worth counties. It is commonly referred to as the "River City", as the city grew up centered on the Winnebago River.


The region around what would later be first called "Shibboleth" was a summer home to the Sioux and Winnebago natives. The first settlement was made at Shibboleth in 1853 at the confluence of the Winnebago River and Calmus Creek. The town had several names: Shibboleth, Masonic Grove, and Masonville, until the name Mason City was adopted in 1855, in honor of a founder's son, Mason Long.

In 1854, John McMillin opened the first store, and Dr. Silas Card opened the first medical practice in the area. Lizzie Thompson established the first schoolhouse in a log cabin in 1856. The United States Post Office Department started service to the town in 1857. Mason City was named as the county seat in 1858.

Mason City, above all else, is known for its outstanding musical heritage, consistently producing successful performers and educators. Mason City's "favorite son" Meredith Willson grew up in Mason City, having played in the Mason City Symphonic Band as a student at Mason City High School. Willson's crowning achievement was the famous musical The Music Man, which was first a successful Broadway musical, then a popular film. Many of the characters in it were taken from people Willson knew from his childhood in Mason City. The show first opened on Broadway in 1957 and became a hit, with a three-year run at the Majestic Theatre, followed by an additional 1,375 performances at the Broadway Theatre. The Music Man garnered many awards, including 5 Tony Awards in 1958. The 1962 film version starred Robert Preston, Shirley Jones, and Buddy Hackett. It was both a critical and commercial success, being nominated for six Academy Awards (including Best Picture) and winning one (Best Musical Score).

Architecture and the Prairie School

Mason City is widely known for its collection of Prairie School architecture, 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.

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.

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. 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 will reopen both buildings as a boutique hotel in August 2011. 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.

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.
