In recent years it has been possible to restore some 9th-century frescoes with classical motifs. The cloister is also worth seeing as are the abbot gallery, the Kaisersaal (imperial hall) and the royal library.
Hoffmann von Fallersleben worked as a librarian in Corvey Castle from 1860 until his death in 1874. The writer of the text of the German national anthem is buried in the small graveyard directly beside the church.
The Baroque castle complex also houses the Regional Museum of Höxter-Corvey (including changing exhibitions) as well as the Institute for the History of Books and Libraries.
Unfortunately the palace garden is not open to the public and is hidden behind a high wall. It can only be admired from the castle forecourt or by looking through the large garden gate.
