Kiel Transmission Tower, Transmission tower in Kiel, Germany.

Kiel Transmission Tower is a 230 meter tall concrete structure with a distinct operational platform situated 108 meters above ground and spanning 40 meters across. The base tapers into a conical shape with a 31 meter diameter, anchored deeply into the ground to ensure stability during various weather conditions.

The tower was built between 1973 and 1975 based on designs by architects Gerhard Kreisel and Günter H. Müller, replacing an earlier 1956 transmission structure that stood only 54 meters tall. This construction project was part of a larger modernization of broadcast infrastructure across the Schleswig-Holstein region.

The tower's name in German, Fernmeldeturm, simply means telecommunications tower, and locals also call it the Fernsehturm Kiel. Its 40-metre basket, with a shell inclined at 18 degrees, was cast using prefabricated parts; the same shell design was not reused for the copies in Bremen, Münster and Cuxhaven because of copyright reasons.

The tower is highly visible from many locations across the city and can be easily spotted in clear weather conditions. Visitors should know that interior access is generally not permitted, as this is an active broadcasting facility with security restrictions in place.

Copies of the tower were built in Bremen, Münster and Cuxhaven, but the precast conical shell of the Kiel operating platform was not reused there for copyright reasons. The Kiel tower is 226.9 metres high, making it the second-tallest structure in Schleswig-Holstein after the 249-metre Bungsberg transmitter.
