These towers are located in Lauchhammer, Germany. They are called The Bio Towers. These towers were built around a central staircase in sets of four. Originally the towers were used to purify wastewater from town’s cooking plant. Then these towers were renovated by cottbus firms jähne & göpfert and zimmermann & partner. The renovation took about two years. One of the towers was equipped with two glazed building turrets. They give visitors a special view of the towers and the former coking plant site. The coking plant’s old geometrical grid structure has been recreated in concrete crosses. It shows visitors how the bio-towers were once part of a much larger facility.
The structures of these towers are used to educate the people about the area’s industrial history through guided tours, exhibitions, and recently glass-sided viewing box. That box offers an elevated view of the complex to the visitors. It’s attached to the top of some of the columns. The bio-towers was opened for visitor in 2008. In 2009, the renovated of these towers were awarded the brandenburgischer ingenieurspreis and the region’s own prize for listed structures
