Home > KVLY-TV mast


The KVLY-TV mast (formerly the KTHI-TV mast) is a television transmitting tower in North Dakota, and at 2,063 ft (628.8 m) it is currently the tallest man-made structure in the world (see also World's tallest structures and List of the world's tallest structures).

Located three miles west of Blanchard, North Dakota (at 47° 20' 32" N, 97° 17' 20" W), it became the tallest artificial structure upon the completion of its construction on August 13, 1963. It was surpassed by 18 m (57 ft) in 1974 by the Warszawa radio mast near Konstantynow, Poland, which collapsed on August 10 1991, making the KVLY mast again the tallest. When (and if) built, the Burj Dubai, presently slated for completion in 2008, might surpass the mast as the tallest land structure.

The tower was built by Hamilton Directors and Kline Iron and Steel, and took thirty days to complete, at a cost of a half million dollars.

Owned by the Meyer Broadcasting Company (now North Dakota Television, LLC) of Bismarck, the tower broadcasts at 316 kW for television station KVLY (channel 11, an NBC affiliate) which is based in FargoFargo is a city located in Cass County in the US state of North Dakota.
