150118 Petersberg           Discovered 1993 Sept. 18 by F. Borngen and L. D. Schmadel at Tautenburg.
The Petersberg is a 250-m hill near of Halle (Saale), Germany. On the hill is an Abbey with its church St. Peter, formerly an Augustinian monastery. Since 1999 it has been an evangelical monastic community. The church served as a burial-place for members of the House Wettin, one of the oldest dynasties of German nobility.
