Its typical floor has an area of 144 m2, there are 14 floors and three platforms. It is located at 42.67667°N, 23.34194°W, at 595 m above sea level.

In 1962 the Borisova Gradina TV Tower was the place from which the first Bulgarian VHF radio broadcast (of the Bulgarian National Radio's Programme 1) was realized. Programme 2 of the BNR's broadcasting began in 1965, and Programme 3's in 1971. BNT's Kanal 1 transmitter was replaced with a more modern conforming to the OIRT colour television requirements in January 1972, and the broadcasting of Efir 2 began in 1975.
