Rheinturm

The Rheinturm (Rhine Tower) is a 240.5 meter (789 ft) high telecommunications tower in Düsseldorf, Germany. It is Düsseldorf's tallest structure and a prominent landmark of the city.

The tower, designed by architect H. Deilmann, was completed in 1981. It houses a revolving restaurant and observation deck offering panoramic views of Düsseldorf and the surrounding Rhine-Ruhr region. The revolving restaurant is located at a height of 172.5 meters and completes a full rotation approximately every 72 minutes.

The Rheinturm is also known for its unique lighting installation, the "Lichtzeitpegel" (Light Time Level), which is considered the world's largest digital clock. The Lichtzeitpegel consists of 39 light points arranged vertically along the tower's shaft. The lights are controlled to display the current time, making it a functional work of art. The clock was designed by Horst H. Baumann.

In addition to its telecommunications and tourism functions, the Rheinturm serves as a radio relay station and supports various mobile communication networks. It is a significant piece of Düsseldorf's skyline and a popular tourist attraction.
