Dr. Salsbury's Laboratories, Charles City

Dr. Salsbury's Laboratories, Main Office and Production Laboratory Building, also known as the Floyd County Museum, is a historic building located in Charles City, Iowa, United States. It was listed on the National Register of Historic Places in 1996. The two-story brick Modern Movement structure is built over a raised basement. It was designed by Waterloo architect Mortimer Cleveland. The facility was built in three parts. Completed in 1935, the part of the building that faces Gilbert Street housed administration and company related operations. The wing off the back was completed two years later, and housed research laboratories and related uses, and offices. To the west of the original block is a single-story wing built after the facility became a museum in the 1990s. ()
