The coat shows the sky tent with all the signs of the zodiac embroidered with gold threads on the original purple background. The stars spread radially over the entire cloak, coming from the Christian centre.
Not only Henry II, but also his wife Cunegonde donated valuable items to the diocese: Relics, books and liturgical treasures.
Over the centuries, the cathedral treasure was expanded by various bishops and canons. A further showpiece of the preserved treasure, in addition to the star-shaped mantle, is the magnificent Cathedral Cross, which is solemnly carried through the streets of Bamberg every year during the Corpus Christi procession. Today, the original sculptures of the cathedral portals are also housed in the Diözesanmuseum and can be seen in the cloister.
