The crypt of the collegiate church of St. Servatius in Quedlinburg is one of the most beautiful rooms of its kind in Europe. It was built between 1070 and 1129 in the course of the new construction of the church, including older parts.
The vaulting paintings were also created as early as the 12th century and are thus among the oldest surviving wall paintings in Germany. They depict scenes from the Old and New Testaments, as well as individual saints and historical figures, including a bishop and a male ruler, the latter inscribed as OTTO MAGNUS.
