Architecture buffs will want to pay a visit to this housing estate built for a building exhibition in 1927. Walking through the estate you see houses created by architects such as Ludwig Mies van der Rohe (Am Weissenhof 14–29), Le Corbusier (Rathenaustrasse 1–3), and Hans Scharoun (Hölzweg 1). Many of the houses represent the functional style that was being promoted by the Bauhaus school of art and design. Displays in the small Architektur-Galerie, Am Weissenhof 30 tel. 0711/257-1434;, provide information about the project and the architects involved; the gallery is open Tuesday through Saturday 2 to 6 p.m. and Sunday noon to 5 p.m.; walking tours are available on Saturdays at 11am (call first to confirm). To reach the Weissenhof Estate, take a taxi or the U-Bahn line 7 to the Killesberg-Messe stop and walk northeast around the Messe into the residential neighborhood. For a private architectural tour by an English-speaking city guide/taxi driver, call Anselm Vogt-Moykopf at tel. 0172/740-1138 (
