The historic ensemble of building with its baroque character is a former hunting lodge. In 1783, it was built as a summer and hunting residence by Prince Ludwig of Nassau-Saarbrücken.

towards the end of the Middle Ages, the primary function of the Reichs-Fortress was to oversee the Kaiserstrasse (Emperor´s Road), the main road connecting Paris with the Rhine river.

Montclair castle is situated near Mettlach, on a long stretched ridge amidst the so called Saar Bend, where the river meanders through the Saar valley in a horseshoe-shaped loop.
