 This former manor was supposedly thus named ("Trümmer" = rubble, "Hof" = court, yard) because it was built on top of Roman ruins.The village was inhabited primarily by vintners and day labourers, who served land-owning monasteries and rich members of Vienna’s bourgeoisie.In the 14th century, the last of the Grunzinger, Rüdiger von Gründsing, died, and in 1350 he was buried in the Minoritenkirche in Vienna.
