The house served as a "House of Parliament" and the agreement from 1883 that made Lüderitz and the surrounding land (radius of 8 km) be owned by Angra Pequeña was signed by Heinrich Vogelsang, the represantative of the trader FAE Lüderitz, here. On 28 Oct 1884, a meeting was held in the Raadsaal of the the house. The German Consul-General Dr Gustav Nachtigal signed the first "Schutzvertrag" (protection treaty) between the people of Namiba and the Germans with the Nama Council. In 1906 the house was confiscated by the Witboois. Until the 1970s it was let to different people and decayed. Unique example of pre-colonial building methods and the best preserved example for the archtecture of that time, especially the interior roof construction. "Parliament" and residence. Since 1990, it serves as a Council Chamber and cultural center to the Nama community.
