On you visit to Rocky Mountain National Park, did you stop at Holzwarth Never Summer Ranch? Most likely you did because it is the most visited historic site in the park. Similarly, many visitors stop at Moraine Park Museum, which is housed in the former assembly hall of the Moraine Park Lodge. At Holzwarth Ranch and at Moraine Park, historic buildings have been preserved to allow visitors to experience some of Rocky Mountain National Park's cultural history. But historic buildings in the park are used for more than just museums. Park staff uses many other historic structures for offices, workshops, barns, and housing.
A historic building is listed on or eligible for listing on the National Register of Historic Places, the nation's official list of cultural resources. All the public and private buildings found on its rolls have been evaluated and documented according to uniform standards established by the National Park Service. Once listed, a public building can not be dramatically altered without approval from the State Historic Preservation Officer (SHPO).
