Leopoldsberg, Vienna, Austria

At Heiligenstadt train station you'll be faced with Karl Marx Hof[a], an aptly named brutalist style[b] building.

Looking down at Vienna from Leopoldberg. The river is of course the Danube, with the Old and New Danube rivers on each side of the Donauinsel ("Danube Island")[c]. The Leopoldberg was the site of the Battle of Vienna[d], where the Holy League[e] routed the forces of the Ottoman Empire[f] in 1683.

On top of the Leopoldberg is this memorial to Austrian prisoners of war from the second world war.

View down toward Vienna from the memorial.
