Two types of historic district designations exist in Telluride: a local district, which is established by Town Council, and a National Historic Landmark District.

The designation of the core of Telluride as a National Historic Landmark District is important. This listing is the highest level of recognition given by the Secretary of the Interior. These sites are so special that they are eligible for consideration for development as National Parks. As a National Historic Landmark, the town is also listed on the National Register of Historic Places, a list of sites and properties of historic significance that reflect our country’s heritage. The National Park Service administers the National Register and the Landmarks program, and nominations are submitted through the State Historic Preservation Officer, using criteria adopted by the Secretary of the Interior.
