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.
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 reopened 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.
