The series "Regions in North Rhine-Westphalia" provides an impression of the diversity of the state. In eight volumes, the various cultural landscapes are presented in words and images. Following a general introduction, the individual cities and municipalities are described, including their geographical location, history, sights, cultural offerings, economic structure, customs, and notable personalities. Numerous contact addresses are included to encourage readers to get to know the regions better. Each contribution is rounded off with the respective city or municipal coat of arms and many color photos. The series begins with a description of Sauerland, Siegerland, and Wittgensteiner Land. Due to their topography, these landscapes were long situated away from the main traffic routes, and correspondingly, their development was limited—especially after the exhaustion of the ore deposits.
