Das Buddhistische Haus (engl.: the Buddhist house) is a Theravada Buddhist temple complex (Vihara) in Frohnau, Berlin, Germany. It is considered to be the oldest and largest Theravada Buddhist center in Europe and has been declared a National Heritage site. The main building of Das Buddhistische Haus was designed by the architect Max Meyer for Dr. Paul Dahlke, a German physician who had undertaken a number of trips to Ceylon prior to World War I and became a Buddhist. It incorporates elements of Buddhist culture from several Buddhist traditions and was completed in 1924.Under Dahlke's direction it became a center of Buddhism in Germany. After the war Asoka Weeraratna, founder of the German Dharmaduta Society, became aware of its existence. In December 1957 he bought the building converted it into a Buddhist Vihara. Missionary Buddhist (Dharmaduta) monks, primarily from Sri Lanka, have come to stay at the Haus since 1957. It has now become an important center for spreading the teachings of the Buddha in Western Europe.[4
