The abbey was founded by Benedictine monks who came from the Isle of Iona, off the west coast of Scotland. It houses a museum showing works from the 15C-19C, including some by Rubens and Biedermeier, as well as the famous altarpiece of the Scots, a Flamboyant Gothic masterpiece from c 1470 that includes depictions of medieval Vienna. A very old statue of the Virgin Mary (c 1250) stands in the church.
