There are two burial sites on the Schwanberg, the vault of the princes of Castell, as well as the cemetery of the Protestant order Communität Casteller Ring. The latter emerged shortly after the 2nd World War from the Bavarian Girl Scout Movement Bund Christlicher Pfadfinderinnen (BCP - there is a German Wiki article about it). Members are still living on the mountain, where they maintain a retreat, the Geistliches Zentrum Schwanberg (Spiritual Center Schwanberg).
