The Genovevaburg castle is home to the Eifelmuseum and the Deutsches Schieferbergwerk, or German slate mine.
The Mayen castle festival is held every summer in the castle courtyard.

The Genovevaburg castle is one of the landmarks of the town of Mayen and can be seen from far and wide on a crest of rock above the market square. The late Gothic castle has been besieged, destroyed and rebuilt several times during its eventful history.

The current site consists of the Oberburg, or upper castle, with its 34m-high Goloturm tower, and the Vorburg, or forecastle, which is slightly lower down. Facing the town, the castle is protected by a large castle gate, and to the other sides by the castle keep and an outer ward.
