The Sprague, Brown, and Knowlton Store is a historic building located in Winterset, Iowa, United States. Built in 1866 to house a dry goods store, it is an early example of a vernacular limestone commercial building.[1] The two-story structure is composed of locally quarried ashlar and rubble stone. It features chamfered quoins and jambs, and a bracketed stone cornice. Its construction has been attributed to local stonemason David Harris.[1] The storefront has subsequently been altered. The building was individually listed on the National Register of Historic Places in 1987, and it was included as a contributing property in the Winterset Courthouse Square Commercial Historic District in 2015.[2]
