The TV tower on Avala hill, near Belgrade, was built in 1965. It was
designed by architects Ugljesa Bogunovic and Slobodan Janjic and the
project of structure was done by engineer Milan Krstic. The total height
of the tower was 202.87 meters. It was the only tower in the world with
the section in the form of equilateral triangle, with reinforced angles
of the spherical section. The three poles of the tower were jointly
leaning on the foundation block which was 1.4 meters buried into the
rock. During the years, it became one of the symbols of Belgrade.
The NATO planes bombed it on 29th April 1999 at 22:40 hours.
