The Lüntec Tower (also called Colani Egg or UFO) is the futuristic redesign of a winding tower of the former Minister Achenbach coal mine in the Brambauer district of Lüner.
After mine 4 at the Minister Achenbach colliery was shut down in 1990, RAG used the site for apprentice training until 1992. The Lünen Technology Center, or Lüntec for short, was then built in the administration and Kauen buildings built in 1922 and was founded on October 11, 1991. The renovation work that began in 1993 was completed in May 1995 with the placement of the Colani egg on the winding tower.
The object, designed based on a sketch by designer Luigi Colani, is intended to clearly illustrate the structural change in the Ruhr area. On the Industrial Heritage Route it is one of several themed routes.
The “UFO” has been shining in new splendor since mid-2009. After extensive renovation work, a business lounge was created at a height of 35 meters with a panoramic view of Lünen and the surrounding area. The shaft hall became the foyer and is used as an event room.
In 2008, the ensemble was expanded to include the Black Cube, which expanded the technology center's office space. In this context, it received the Artwork of the Year 2009 award from the Lünen Art Association.
At RUHR.2010, the building ensemble was presented together with other art and cultural objects as part of the Shining Heads of the Lippe Region project.
