The Indemann was designed by the Maastricht architecture firm Maurer United Architects as a symbol of the structural-political evolution of the former mining region near Inden. This 36 meter high, accessible steel sculpture, built on a brown coal dump, resembles in its form a primitive robot. The Indemann gets its unique brightness from Illumesh® - a semitransparent skin made of stainless steel mesh with interwoven LED profiles by GKD – Gebrüder Kufferath AG. During the day, the metallic surface shimmers and reflects light, then at night a computer-controlled light show comes to life. The worldwide patented system is a cooperative product of GKD and ag4 media facade GmbH, Cologne. The Indemann is the first public project in Germany where Illumesh® is in use. After the spectacular dress rehearsal at the beginning of August, which attracted already over 2.500 spectators, the official inauguration of the steel colossus is on September 5th.
