Tater Knob Fire Tower near Morehead has been closed because it was damaged by fire, Daniel Boone National Forest officials said Thursday.
The cab at the top of the tower was burned. Officials said they did not know how the fire started.
It was the last fire tower left in the national forest, and it was listed on the National Historic Lookout Register.
The tower was built in 1934 by the Civilian Conservation Corps. It was staffed daily during fire seasons through the early 1970s. Now, planes provide lookout duties.
In 1993, the tower was restored and opened to the public.
