History+
The origins of the abbey date back to 1372, when a chapel was built on this site. In 1400, this was expanded to include the construction of a crypt. The official founding of Dürnstein Abbey took place in 1410. A turning point was the dissolution of the monastery under Emperor Joseph II in 1788. As a result, the buildings and land holdings were transferred to the Augustinian Canons Regular of Herzogenburg Abbey, which remains responsible for the parish of Dürnstein to this day.
