Yes, the Friends of Cedar Rock were in Grinnell on Saturday. Yes, they had a great visit and loved the tours of the Sullivan Bank and Ricker House.
But, they are on a greater mission. They are marking the 100th anniversary of the first Prairie School buildings in Iowa.
In 1908, Frank Lloyd Wright was in Mason City, developing plans for a downtown business block that would feature an adjoining bank and hotel — which would become the Park Inn (the only surviving Wright hotel in the world) and the City National Bank.
During that time, he was asked by a local doctor, George Stockman, to design a four-bedroom house which was completed that year.

Work began on the bank and inn the following year, but Wright left the US for Europe that October. His chief draftsman, William Drummond, supervised the construction and the project was completed in 1910.
Local leaders had also been discussing with Wright the possibility of a housing development. His decision to leave for Europe with the wife of a client scuttled those plans. In 1911, they suggested to Wright’s talented draftswoman, Marion Mahoney Griffin, that she consider taking on the project. She recommended that her husband, Walter Burley Griffin, get the job.
Griffin had also worked for Wright. He had earlier designed projects in Grinnell, including a fountain in Central Park and a home, the B.J. Ricker House. He also had ideas for a housing development north of Ricker House. Griffin took an 18-acre parcel, formerly a garbage dump, along Willow Creek in Mason City and created the Rock Crest, Rock Glen development. It remains the largest collection of Prairie Style homes surrounding a natural setting.
Other Prairie School architects designed homes in Rock Crest, Rock Glen, including Drummond, Barry Byrne and Curtis Besinger. Wright would return to America and design other houses in Iowa communities such as Oskaloosa, Marshalltown and Quasqueton. But his first — and the first of the Prairie School — came 100 years ago in Mason City.
