The brown coal area with its opencast mines and power stations offers an impressive technological sight-seeing programme. In the three open-cast mining areas of Garzweiler, Hambach and Inden, the things to admire are not only steel giants, but also alternative energies and recultivated areas such as the well-loved local recreation area Marienfeld, where the Pope Benedict XVI’s closing church service at the World Youth Day 2005 was celebrated. Exhibitions about the topic brown coal can be visited in historic ambience in the Château Paffendorf and in modern design in the visitors centre of the RWE Power AG in Niederaußem, directly at the power plant. For groups Rhein-Erft Tourismus e.V. offers tours dedicated to brown coal.
