Clingmans Dome Observation Tower
Why it's listed
Clingmans Dome Observation Tower crowns the highest peak in Great Smoky Mountains National Park, straddling the North Carolina and Tennessee border. Completed in 1959 to a design by the Bebb and Olson firm, it is built mainly of reinforced concrete. A 375-foot spiral ramp, rising at about a 12 percent grade like the trail leading to it, carries visitors 45 feet up to a circular platform beneath a flat canopy. Seven concrete columns of varying height support the ramp, and a large hollow central column carries the platform. Stone walls and a flagstone terrace mark the entrance. The tower reflects the National Park Service's Mission 66 program, a ten-year effort to modernize park facilities for growing crowds, and it is one of only nine towers built under that program. Its design drew criticism from conservation groups, and it later served as the pattern for towers at Look Rock and Shark Valley.
Significance in brief: The tower is argued to be nationally significant under Criterion A as an example of the National Park Service's Mission 66 program, in which only nine towers were built. Under Criterion C it represents mid-century Park Service Modern architecture. Its design also served as the model for two later Mission 66 towers, at Look Rock and Shark Valley.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
