Kloster Ebersberg, Benedictine monastery in Ebersberg, Germany

Kloster Ebersberg is a former Benedictine abbey founded in 934 on the site of Ebersberg Castle. Its church, St. Sebastian, is now the Catholic parish church; the monastic buildings house the tax office and the Schlossbrauerei Ebersberg brewery administration. The complex was rebuilt after a major fire in 1781.

The monastery was founded in 934 by counts Eberhard and Adalpero von Sempt. In 1013 it transitioned from an Augustinian chapter to a Benedictine abbey, marking a shift in monastic rule and community structure.

The monastery is dedicated to the Virgin Mary and Saint Sebastian, not Saint Eberhard. Its main cultural draw was the relic of Saint Sebastian's skull, given by Pope Stephen VIII to provost Hunfried, which made Ebersberg one of southern Germany's most important Sebastian pilgrimage sites.

The former monastery buildings now house the Ebersberg tax office and the administration of the Schlossbrauerei Ebersberg, so interiors are not visitable as a museum. The monastic church of St. Sebastian serves as the Catholic parish church. The complex stands in the town centre of Ebersberg, Upper Bavaria, near the Bahnhofstrasse, where a large monastic court was built in 1495.

In medieval times, a relic of Saint Sebastian's skull drew pilgrims from across the region, especially during plague outbreaks when people sought divine protection. This sacred object transformed the site into one of Bavaria's major pilgrimage destinations.
