The Millennium Tower, the highest wooden tower in the world, was built in Magdeburg, Germany for the 1999 Federal Garden Show. It houses a unique exhibition which leads the visitors through the history of human science and research. The timberwork was done on a LIGNAMATIC by Holzbau Amann GmbH.
Using their LIGNAMATIC, Amann specializes in eccentrically-shaped structures from towers to churches. You can see many more projects on their website (in German only; explore the links under "Ingenieur Holzbau" for a variety of engineered wooden structures).
