Konstantynów (Płock County)
From Wikipedia, the free encyclopedia
Konstantynów is a village in Płock County, Masovian Voivodeship, Poland.
From 1974 to 1991 the tallest structure mankind ever built stood here, the Warsaw radio mast. This mast was a 646.38 metre high guyed radio mast in steel-framework construction with triangular cross section with a side length of 4.8 metres and a weight of 420 tons. This mast was used for the 2000 kilowatt longwave transmitter of the Polish broadcasting authority as aerial and was therefore insulated against ground for a voltage of 120 kilovolts. It collapsed during renovation work on August 8th, 1991. Nobody was killed in this accident.
