The site consists of the station building with its exceptional transmitting system, surrounding buildings and the antenna plant (six 127 m high steel towers). The architect Carl Åkerblad designed the main buildings in the neoclassical style and the structural engineer Henrik Kreüger was responsible for the antenna towers, the tallest built structures in Sweden at that time. The site is an outstanding example of the development of telecommunications and is the only surviving example of a major transmitting station based on pre-electronic technology.

The history of technology
The Alexanderson transmitter consists of four systems and was originally produced at General Electric, in USA. In the early 1920’s, it was shipped to Sweden and put in use. The system allowed Morse signals to travel on a certain frequency, which in Grimeton’s case was 17,2 kHz.
