The Michelsburg Castle and the neighboring former provost church of St. Remigius on the Remigiusberg near Haschbach in the center of the Glan Valley are the historical heart of the Remigiusland region.
In 1127, an illegally built hilltop castle was documented when Benedictine monks purchased it from a knight named Adelbert.
The monks used the stones of the former castle to build the Benedictine provost church of St. Remigi, a branch monastery of the Abbey of St. Remy near Reims.
The remnant of this provost church is the Remigius Church.
In 1543, Count Palatine Rupert of Veldenz had a princely crypt built in the provost church.
The crypt contains the remains of 14 members of the princely family.
The monastery was dissolved in 1550 during the Reformation.
Of the original Romanesque, three-aisled, cross-pillar basilica, only part of the central nave, a stone chapel, and the bell tower remain today.
Remains of the former monastery complex are located beneath the sacristy and the restaurant rooms.
The boundary wall of the restaurant terrace is the remains of the southern wing of the monastery.
The name Remigius is a reference to Saint Remigius, Bishop of Reims.
