Hoher Peißenberg, Mountain summit in Pfaffenwinkel region, Bavaria, Germany

Hoher Peißenberg is a 988 m high, partly wooded ridge in the Pfaffenwinkel region of Bavaria, extending east to west. Its summit holds the pilgrimage church of Mariä Himmelfahrt, a double church whose earliest part is a chapel from 1514, and the Hohenpeißenberg Meteorological Observatory. A 158.76 m concrete radio tower, built in 1978, stands just below the summit near the hamlet of Pröbstlsberg.

A chapel was founded on the mountain in 1514 and later expanded into a larger pilgrimage church. At the same time, a weather station began taking measurements in 1781 and continues operating today.

The pilgrimage church of Mariä Himmelfahrt holds a chapel from 1514, later enlarged into a double church. Each summer a Trachtenwallfahrt, a pilgrimage in traditional costume, takes place. Since 1990 the Schatzkammer museum in the oratory above the sacristy can be visited by telephone appointment.

Several marked trails lead to the summit, allowing visitors to choose a route suited to their fitness level. The mountain is accessible year-round on foot, though winter may bring snow that affects hiking conditions.

On clear days, visitors can identify more than 400 different locations and landmarks from the summit, including well-known lakes and distant mountain ranges. This makes the place popular with photographers and nature observers eager to explore the panorama.
