This picture book invites you on a colorful journey through the rustic low mountain landscape of the Sauerland. The atmospheric color photographs by landscape photographer Holger Klaes and other renowned photographers guide you through enchanting mountain forests, charming valleys, past Germany's only high moor to the weather station on the Kahlen Asten and to the Hohe Bracht. The underground beauty of the stalactite caves is just as characteristic of the Sauerland as the abundance of reservoirs, which include the Hennesee, the Sorpetalsperre, and Germany's third-largest dam, the Biggesee. Significant buildings, such as the castles of Bilstein and Altena, Baroque churches, and valuable art treasures shape the Sauerland, as do the market squares and half-timbered facades of the towns of Arnsberg, Brilon, Olpe, Lüdenscheid, and Hagen, to name just a few. The author is Ferdinand Fi.
