The Princely Abbey of Corvey (German: Fürststift Corvey or Fürstabtei 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.
Corvey thus became "one of the most privileged Carolingian monastic sanctuaries in the 9th-century Duchy of Saxony". It soon became famous for its school, which produced many celebrated scholars, among them the 10th-century Saxon historian Widukind of Corvey, author of Res gestae Saxonicae. From its cloisters went forth a stream of missionaries who evangelised Northern Europe.

The site of the abbey, where the east-west route called the Hellweg crossed the Weser, was of some strategic importance and assured its economic and cultural importance. The abbey's historian H. H. Kaminsky estimates that the royal entourage visited Corvey at least 110 times before 1073, occasions for the issuance of charters.
The famous abbey library has long since been dispersed, but the "princely library" (Fürstliche Bibliothek), an aristocratic family library, containing about 74,000 volumes, mainly in German, French, and English, with a tailing off circa 1834, survives in the Schloss. One striking feature of the collection is the large number of English Romantic novels, some in unique copies, for in Britain fiction was more often borrowed than bought, and was read extensively in the lending libraries. The poet and author of the Deutschlandlied, August Heinrich Hoffmann von Fallersleben, worked here as librarian from 1860 until his death in 1874. He is buried in the church graveyard.(Source: Wikipedia)
