Since June 2004, Manubach has had a museum to commemorate the life of the Manubach pastor and writer Wilhelm Oertel, alias W. O. von Horn. The museum is housed on the groundfloor of the old vicarage, at Auf der Schadenbach 2. The manuscripts, books and pictures from Oertel's time (19th century) are on show. The museum is supported by the Protestant parish of Oberdiebach-Manubach.
