Langer Eugen significant event construction
Langer Eugen (English: "Tall Eugene") is an office tower in the Gronau district of Bonn, Germany.  It was built between 1966 and 1969.  Since 2006 it has housed several United Nations organizations.  Until the German Bundestag (parliament) moved to Berlin in 1999, the building was the primary location for the offices of the members of the Bundestag.  After renovations, eleven UN organizations moved into the building and it began serving as the center of the UN Campus, Bonn. Langer Eugen is protected as a landmark or listed building under the North Rhine-Westphalia Monument Protection Law.  It is currently the second-tallest building in Bonn and the 43rd tallest building in Germany (excluding non-habitable structures such as radio and observation towers, steeples, and chimneys).  When it was built it was briefly the second-tallest building in Germany, behind the Bayer-Hochhaus.
