The Kölnturm (own spelling KölnTurm ) is at 148.1 meters (165.5 meters with antenna) the tallest office building in Cologne . It was built in two and a half years, from June 1, 1999 (laying of the foundation stone) to November 21, 2001 (inauguration), in Cologne's Mediapark . The building ensemble in the Cologne-Neustadt-Nord district is intended to upgrade the city of Cologne as a media location and offer companies from the sector office, congress and conference rooms.
After the Post Tower in Bonn, the Kölnturm is the second tallest high-rise in North Rhine-Westphalia and ranks sixteen in the list of high-rise buildings in Germany .
The roof terrace on the 30th floor is open to the public for visitors to the restaurant there.
architecture
The reinforced concrete building was created in collaboration between the architecture firm, renamed from Kohl & Kohl in Kohl: Fromme in 2005, and the Parisian architect Jean Nouvel . It contains a load-bearing central core and pendulum supports towards the edge of the individual floors . Construction began in 1997, construction work was interrupted in 1998, and the inauguration took place in summer 2001. An 18-meter-high transmission mast forms the upper end of the tower, which is divided into three different floor plan areas.
The tower has a total of 43 floors, which can be reached by six elevators at a speed of five meters per second.
The glass facade of the building was designed with a new type of technology in order to achieve a reflective effect: depending on the light irradiation, the screen-printed and burned-in images change in color and shape. The Cologne Cathedral and the silhouette of Cologne's old town with a cloudy sky were chosen as motifs .
Transmitter location
Three VHF frequencies are broadcast from the antenna mast on top of the Cologne Tower, mainly for the northern districts of Cologne. On 98.6 MHz with 400 watt WDR 2 regional window Cologne and on 87.6 MHz with 300 watt WDR 1LIVE . Until August 2, 2010, Germany radio culture with 30 watts was broadcast on 89.9 MHz . This broadcast was given up after Deutschlandradio Kultur took over the high-coverage frequency 96.5 MHz from BFBS Radio on the Langenberg station . Despite the low transmission power, the frequencies can be received in sufficient quality in the northern parts of the city due to the exposed antenna height. Since 2002, the Kölnturm has replaced the former VHF transmitter location on the nearby, lower Hansa high- rise on Hansaring. Other VHF transmitter locations in Cologne are the telecommunications office in Sternengasse , the Colonius television tower and the Pollonius radio tower in the Poll district.
Digital radio (DAB / DAB +)
DAB or the successor standard DAB + is broadcast in vertical polarization and in single-frequency mode with other transmitters. On August 29, 2012 the change from DAB channel 12D to DAB channel 11D took place. The multiplex radio for NRW with the programs of the WDR and the cathedral radio with an output of 10 kW ERP is currently being transmitted via this .
