KPN Radio Tower

Tall office and residential towers mark the Zuidas. They are not allowed to be too high; 105 metres is the maximum because of Schiphol Airport’s approach routes. An exception has been made for one structure, namely the transmission tower, built in 1963, in what is now called Vivaldi district. The tower is designed to guarantee the reception of radio and television, mobile telephony and data traffic and it also functions as a disaster transmitter in the event of a calamity. It must therefore tower above all the other structures, which, following a spectacular renovation and extension to a height of 146 metres, it now does.

The tower is a new element on the city’s skyline. It is adorned with five intriguing oval platforms, which differ in size and are slightly staggered in relation to each other. The necessary dish antennae have been attached to the exterior of the lower three platforms. On the fourth storey is the only (glazed) closed space, which is reserved for temporary microwave radio links. An over-measure has been created for the future with the top platform.

In the evening and at night the tower is emphatically illuminated. A pattern of LED lights, designed by Giny Vos, which refers to the starry skies of the universe, has been installed on the platforms. For the sake of air traffic safety, the top of the tower is provided with a red warning light, as a result of which, in addition to the Hemcentrale (176 metres) and Rembrandt Tower (135 metres), the city now has a third night-time landmark.
