Kirche am Steinhof
Updated:
At the top of Baumgartner Höhe, in the Sozialmedizinisches Zentrum[a], is the Kirche am Steinhof[b], or "Otto Wagner Church".
Unfortunately it is open for visiting on Saturday afternoons only and then in the form of a historical lecture from 3pm to 4pm and individual viewing from 4pm to 5pm. Since I was there on a Monday all I have are exterior shots. Close to the church is a memorial and exhibition to the victims of nazi medical "care".
