This is my nomination for Germany's most conveniently located Adult Education Center. It's right on the same square as the opera house.
In August 2007 the Adult Education Center celebrated the 35th anniversary of the opening of their building. Three of the singers from the opera house came to sing at the anniversary celebration, namely Jee-Hyun Kim, Hrachui Bassenz and Leah Gordon. The reason these particular singers were chosen was that all three of them had learned to speak German in language classes here at the Gelsenkirchen Adult Education Center (VHS).
IBA Emscher park dealt not only with the re-use of old industrial buildings but also with new construction, especially in the field of housing and office spaces. One of the best examples of new housing complexes was built in Gelsenkirchen in mid-1990s, at the site of the former factory. The complex was designed by Austrian (Graz) - based architects Michael Szyskowitz and Karla Kowalski.
The Küppersbuschgelände is a 7-hectare large housing area consisting of low-rise houses grouped into three smaller groups. Special attention was given to ecology, sustainability, energy efficciency and design of open spaces. Hear of the neighbourhood is a large park, and most of the buildings have the view of it. Water from the rooftops is recycled and used for watering the lawns and filling the small artificial lake.
There are some more pictures from this housing complex in an album on this page. I guess even if you are not an architect this place would be interesting to visit for its creativity.
The concrete - glass cubus of the Galerie Architektur und Arbeit in Gelsenkirchen was built in the courtyard next to one of the old winding towers that served extensive network of underground mine galleries. Close to the winding tower there is a beautiful art nouveau machinery building, that was built in 1908. Both the winding tower and the machinery building were preserved and in 1994 a new cubus made of concrete and glass was added, designed by architects Herbert Pfeiffer and Christoph Ellermann.
The Galerie Architektur und Arbeit houses occasional meetings, workshops, advanced trainings as well as exhibitions. The modern building is linked with the old machinery hall that is turned into a large exhibition hall, still displaying original art nouveau decorations and industrial ceiling installations.
When we were here there was an exhibition of architectural students works on the subject of new synagogue and their research on the meeting of the different cultures. The entrance was free (although I'm not sure this is the case with all exhibitions.
Open Tue - Sun 11-17 h
