Hoyt Radio Tower
Hoyt Radio Tower is the tallest man-made structure in Colorado and one of the tallest buildings in the world. Hoyt Radio Tower is a tall guyed mast near Hoyt, Colorado.
It was built in 2003 by Acme Towers, LLC, and is currently owned and operated by the Denver Radio Tower Company for FM-broadcasting, stations KJHM and KFCO, as well as emergency services. Unlike shorter towers, which are painted red and white in seven alternating bands for aircraft warning, the Hoyt Radio Tower is unpainted and uses strobe lights for aircraft warning.
The Hoyt Radio Tower's basement is situated above sea level, making it not only one of the world's tallest structure but also one of the few supertall structures in the world whose basement is situated at an altitude over.
