The Colorado State Register of Historic Properties, administered by the History Colorado Office of Archaeology and Historic Preservation, is a listing of significant historic resources. History Colorado maintains a list of the Colorado State Register of Historic Properties, which can include archaeological and historic structures, buildings, objects and districts. Properties are added to the state register by nomination to History Colorado. Any Colorado historic sites added to the National Register of Historic Places are automatically included in the Colorado State Register.[1]
The state register includes over 1,700 listings, of which over 1,300 are also listed on the national register.[2]
