The JenTower is a skyscraper in Jena, Germany.
The tower has been known by many names, official and unofficial. From 1992 until January 2005, the tower was called the Intershop Tower after its principal tenant, Intershop Communications AG. On November 30, 2004, the building was renamed the JenTower.
The JenTower stands directly opposite to the so-called Building 15, which was the first German multistoried building. Building 15 was erected in to a height of 43 meters in 1915, based on plans by the architect Friedrich Puetzer .
The architect of the tower was Hermann Henselmann, one of the most famous architects of the former German Democratic Republic. The idea of a monolithic tower as an "urban crown" was developed by Bruno Taut, who was city architect in Magdeburg in the 1920s.
