House of Bismarck in the context of "Prince of Bismarck"

Friedrichsruh (German pronunciation: [fʁiːdʁɪçsˈʁuː] ) is a district in the municipality of Aumühle, Herzogtum Lauenburg district, Schleswig-Holstein, in northern Germany. Friedrichsruh manor is known as a residence of the princely House of Bismarck, mainly of Chancellor Otto von Bismarck from 1871 onwards.

The Sachsenwald (German pronunciation: [ˈzaksn̩valt] ) is a forest near Hamburg, Germany. The forest derives its name, which can be translated as 'Saxon woods' or 'Saxony forest', from being located in the former Duchy of Saxe-Lauenburg, which itself is a part of the greater Lower Saxony region as defined by the former Duchy of Saxony. Today, the forest is an unincorporated area in the district of Herzogtum Lauenburg (Duchy of Lauenburg) in Schleswig-Holstein. It is also a member of the amt Hohe Elbgeest, in which it has non-voting representation. The Sachsenwald has an area of 68 square kilometres (26 sq mi) and is the largest contiguous forest area in Schleswig-Holstein.

Large parts of the forest belong to the House of Bismarck since 1871, who still have their headquarters at Friedrichsruh Castle on the edge of the Sachsenwald.
