Colonius is the name of the Cologne telecommunications tower, which was finished in 1981. The Colonius possesses a cafeteria, viewing platform, and a restaurant, apart from antennas for radio relay and radio services within the UKW range. Unfortunately the visitor's area (including restaurant and viewing platform) is currently closed (2005). At the time of its completion the Colonius was 252.9 meters high. In 2004 a radio tower added by helicopter increased the height to 266 meters. This addition allowed the broadcast of digital cable from the tower in the Cologne-Bonn region.
