Princely Abbey of Corvey

The Princely Abbey of Corvey is a former Benedictine abbey and ecclesiastical principality now in North Rhine-Westphalia, Germany. It was one of the half-dozen self-ruling princely abbeys of the Holy Roman Empire from the late Middle Ages until 1792 when Corvey was elevated to a prince-bishopric. Corvey, whose territory extended over a vast area, was in turn secularized in 1803 in the course of the German mediatisation and absorbed into the newly created Principality of Nassau-Orange-Fulda. In 2014, the former abbey church was listed as a UNESCO World Heritage Site.
