The Municipal Building was designed by a group of local architects – Proudfoot & Bird, Hallet & Rawson, Wetherell & Gage, and Liebbe, Mourse & Rasmussen, and completed in 1909. Built in the Beaux Arts style and clad in Bedford limestone and Tennessee & Vermont marbles, it was the first building reflected in the Des Moines Master Plan. The building was listed on the National Register of Historic Places in 1977. It is currently undergoing a complete renovation.
