text: The "Black Sun" (German Schwarze Sonne) is a symbol of esoteric and occult significance based on a sun wheel mosaic with twelve-fold rotational symmetry incorporated into a floor of Wewelsburg Castle during the Nazi era, which was itself loosely based on swastika-like designs in Migration-period Zierscheiben.
