Klosterneuburg Monastery

Klosterneuburg Abbey or Monastery is a twelfth-century Augustinian monastery of the Catholic Church located in the town of Klosterneuburg in Lower Austria. Overlooking the Danube, just north of the Vienna city limits at the Leopoldsberg, the monastery was founded in 1114 by Saint Leopold III of Babenberg, the patron saint of Austria, and his second wife Agnes of Germany.

The abbey church, dedicated the Nativity of Mary, was consecrated in 1136 and remodeled in the Baroque style in the seventeenth century. The impressive monastery complex was mostly constructed between 1730 and 1834. Its foundations, including a castle tower and a Gothic chapel, date back to the twelfth century.
