Enrique III el Negro
In the external wall of the Baroque church created in the west wing of the surviving monastery precinct, are immured the remains of Beatrice of Gandersheim (d. 1061), daughter of Henry III, Holy Roman Emperor, and abbess of Gandersheim and Quedlinburg. Formerly buried at Quedlinburg Abbey, Beatrice's remains were displaced after the church there burnt down in 1070, and were apparently finally laid to rest in Michaelstein in the 1160s.
