Friedenau () is a locality (Ortsteil) within the borough (Bezirk) of Tempelhof-Schöneberg in Berlin, Germany. Relatively small by area, its population density is the highest in the city. Geography Friedenau is part of the southwestern suburbs, right at the border with the inner city Schöneberg district, separated by the Berlin Ringbahn and the BAB 100 motorway (Stadtring). It borders the Wilmersdorf locality to the west and Steglitz to the south. The streets and squares are laid out according to a geometric urban design with an almost complete assembly of Gründerzeit buildings, which survived the bombing of Berlin in World War II. Urban planning The characteristic feature of Friedenau its Carstenn layout, named after urban developer Johann Anton Wilhelm von Carsten. This symmetrical layout consists of an avenue dividing a circular road, which is demarcated by four town squares. Some streets in Friedenau were named after rivers in Alsace-Lorraine to commemorate the annexation of this region into the German Empire. The majority of Friedenau's buildings date to the early 20th century. Therefore, the architectural styles are almost uniform. 185 buildings are protected as cultural heritage sites. More recent development does not necessarily match the surrounding cityscape, since the reconstruction efforts after World War II, especially in the earlier years, gave little consideration to the preservation of architectural uniformity. History In 1871 it was founded as an affluent commuter town on the estates of the former Deutsch-Wilmersdorf manor. The German name Friedenau, referring to Frieden (peace) and the suffix -au meaning floodplains (hence "floodplain of peace"), was proposed by Hedwig Hähnel, wife of the architect Hermann Hähnel, in memory of the 1871 Peace of Frankfurt, which ended the Franco-Prussian War. It was adopted by Mr. Hähnel, then the director of the Landerwerb- und Bauverein auf Actien (inc.), which developed the real estate in the area. When in 1874 the area constituted as an independent municipality within the Province of Brandenburg, the denotation had already been established and became the official municipal name. Friedenau opened its own non-denominational municipal cemetery, today's Städtischer Friedhof III, which soon grew too small. So in 1909 Friedenau bought a tract of land in Güterfelde (today a component of Stahnsdorf) as additional graveyard, with the first burial taking place in 1913. Friedenau's municipal construction councillor Hans Altmann designed for the cemetery a mourning chapel, an office, a gardener's house, a flower shop, benches and a fountain as well
