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.
The first documented mention of an illegally built hilltop castle dates back to 1127, 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, the remnant of which is the Remigius Church.
Count Henry II of Zweibrücken built a second castle out of wood in 1260 – during the inheritance disputes of the counts of Veldenz – after the first male line of counts of Veldenz had died out in 1259.
Later, this castle was expanded and furnished with stone, and a chapel (dedicated to St. Michael) was built inside.
In 1543, Count Palatine Rupert of Veldenz made the castle his secondary residence and had a princely crypt built in the provost church.
Little is known about what happened to the castle in later centuries, but it was reportedly still intact in 1708 and changed hands several times.
In 1868, it came into the possession of the St. Remigiusberg Catholic Church Foundation.
Today, the 20-meter-high shield wall, remnants of the palace, the ring wall, and the moat are preserved.
