Petersberg, Hill and summit in Saxony-Anhalt, Germany.

Petersberg rises 250 meters (820 feet) above sea level and consists of small-grained stone formed during the Upper Carboniferous period. The summit holds a wildlife park with regional animals, a year-round toboggan run, and a radio transmission tower.

The hill was called Lauterberg until the 14th century, when it took its present name from St. Peter's Church on the summit. An Augustinian monastery, Petersberg Abbey, was founded there, and its collegiate church of St. Peter still stands. Since 1999 an Evangelical monastic community of the Christusbruderschaft Selbitz has used the abbey.

The hill's name comes from St. Peter's Church, and until the 14th century it was called Lauterberg. The Augustinian abbey founded at the summit is now an Evangelical monastic community of the Christusbruderschaft Selbitz, established in 1999. The 15-metre Bismarck tower, designed by Wilhelm Kreis, was inaugurated on 24 September 1902 and renovated in 1999/2000.

The hill is accessible by foot with walking routes of varying difficulty suited to different fitness levels. Wear sturdy shoes since some paths are steep and can become slippery in wet weather.

The E11 European long-distance trail runs from the Netherlands to Masuria and passes near this hill, making it a waypoint on one of Europe's longest hiking routes. Visitors can reach this spot as part of a multi-day or multi-week hiking journey.
