Helmut Jahn of Murphy/Jahn designed the Post Tower as the headquarters of Deutsche Post and DHL. It was built from May 2000 to December 2002, and the infobox gives a cost of 78 million euros. The article calls the style postmodernist.
The tower is 533 feet (162.5 m) tall. The infobox gives 41 floors above ground and the lead gives 42, with five underground levels. Its base is two staggered semi-elliptical shapes made of shifted circle segments. It is built of steel, concrete and glass, with about 93,000 m² of glass. The double-skin facade has a 120-centimeter cavity with blinds for natural ventilation.
Groundwater heats and cools the concrete core. It stands on the Rhine riverside in Bonn's former parliamentary district. It won a Silver Emporis Skyscraper Award in 2002 and is the second tallest skyscraper in Germany outside Frankfurt.
