The Altenburg Abbey – a Benedictine monastery in Altenburg in Lower Austria. The monastery was founded in 1144 by the Countess Hildenburg. The Abbey was built under the guidance of architect Joseph Mungenast in the Baroque style. Many outstanding craftsmen and artists worked on this project: Paul Troger created murals, Franz Joseph Holzinger worked on the stucco, and Johann Georg Hopple was engaged in interior decoration marble.

In 1793, the Emperor Joseph II forbade to accept new novices in the monastery, but unlike many other monasteries in Austria, Altenburg managed to avoid closure.

In 1940, the activities of the Abbey was suspended because of the Nazis, and in 1941 the monastery was completely dissolved, the senior priest was arrested. Since 1945 the building was used as barracks for the Soviet occupation forces.

After the Second world war, the monastery was restored under the leadership of Abbot Maurus Knapek. In 1961, the Abbot moor has created a boys ' choir, which began touring in different countries of Europe, Israel, Japan and Brazil.

Interesting to explore the Treasury of the monastery and library, is particularly distinguished with a unique painting of the walls and ceiling of the Abbey.
