Selnau (from earlier Sellnau, Seldnau) was historically an estate west of the city, which came to lie between the north-western moat (Schanzengraben) and the Sihl. Together with the Gessnerallee, Selnaustrasse and Sihlhölzlistrasse running along the right bank of the Sihl, it is part of the City quarter even though strictly situated outside the city ramparts. Today, Zürich Selnau railway station is a stop on the line of the Uetlibergbahn, running from Zürich Hauptbahnhof to the Sihltal (S4) and to the Uetliberg (S10). The SWX Swiss Exchange building is located in Selnau. The museum Haus Konstruktiv is located in a former power station near Selnau train station.
