Count Frederick Charles Augustus of Lippe-Biesterfeld (20 January 1706 in Biesterfeld - 31 July 1781 in Friedrichsruh) was a Count of Lippe and Lord of Lippe-Biesterfeld, Sternberg, and Schwalenberg and a Knight of the Order of the Red Eagle.
He was the eldest son of Rudolf Ferdinand of Lippe-Sternberg-Schwalenberg (17 March 1671 - 12 July 1736) and Louise Juliane of Kunowitz (21 August 1671 - 21 October 1754) and the grandson of Count Jobst Herman of Lippe-Biesterfeld.
Charles Frederick Augustus was the last Lord of Biesterfeld. During his reign, he had the manor's brewery moved from Schwalenberg to Biestereld and added a distillery, investing 6000 taler in this endeavor.
In 1763, he constructed a hunting lodge in the Sachsenwald forest, near Hamburg, named Friedrichsruh after himself. The nearby village was later renamed after the hunting lodge.[1] However, the hunting lodge was demolished in 1859 to make room for a guest house. Otto von Bismarck was granted the Sachsenwald as a gratification for the foundation of the German Empire in 1871. He expanded the guest house to a castle, which was destroyed during World War II. The new manor house that took its place is still named Friedrichsruh Castle and is home to the current Prince Bismarck.
The manor house and farm at Biesterfeld were demolished around 1820.
