Klosterneuburg was founded by Margrave Leopold III and developed in conjunction with its famous monastery. Leopold III and later Leopold VI (the latter only during part of his reign) had their residences there. From 1938 to 1954, it constituted the 26th district of Vienna. Today, it is a site of industry and a suburb of Vienna. The well-known Essl Museum of contemporary art is also on display in the town.

I found a video on YouTube made by a couple traveling in Austria. It features some lovely images of the village and Monastery.
