IG Farben Building

The IG Farben Building – also known as the Poelzig Building and the Abrams Building, formerly informally called The Pentagon of Europe – is a building complex in Frankfurt, Germany, which currently serves as the main structure of the West End Campus of the University of Frankfurt. Construction began in 1928 and was complete in 1930 as the corporate headquarters of the IG Farben conglomerate, then the world's largest chemical company and the world's fourth-largest company overall.The building's original design in the modernist New Objectivity style was the subject of a competition which was eventually won by the architect Hans Poelzig.
