Two Iowa City cottages dating to the 1850s are being razed after officials declined to seek their designation as historic landmarks. On Wednesday, crews started demolishing the cottages, which will be replaced with a mixed-use development. A third cottage was razed in December. Preservationists had sought to save the cottages, noting that they were among the few historic structures in Iowa City that were used by working-class residents. Two city panels supported seeking historic landmark status, but the City Council denied the request. Alicia Trimble of Friends of Historic Preservation called the demolition "incredibly sad."
