Zircon Tower, Office tower in Wiesbaden, Germany

Zircon Tower is an office building in Wiesbaden featuring a glass facade that rises about 70 meters into the skyline. The structure consists of two connected sections that work together to create a cohesive modern office complex.

The building was constructed in 1973 during a period of economic expansion in Germany. It emerged as part of the modernization wave that reshaped Wiesbaden's urban landscape in the postwar era.

The tower's former name, DBV-Winterthur-Hochhaus, recalls the insurance company that once occupied it; today its main tenant is Topcart GmbH. On the roof, transmitters supply Wiesbaden and the surrounding area with Hessischer Rundfunk programmes, and the display sometimes carries programme information, music titles or web addresses.

The tower stands on Gustav-Stresemann-Ring, about 600 metres from Wiesbaden Hauptbahnhof and 26 kilometres from Frankfurt Airport. It is an office building with a main tenant, so visitors should view it from the street rather than expect interior access. Its height makes it visible from a distance as an orientation point.

The tower carries broadcasting equipment for Hessischer Rundfunk, serving Wiesbaden and the surrounding area; its former name was DBV-Winterthur-Hochhaus. At 70 metres it is the city's second-highest building after the Marktkirche.
