The ruins of Mont Royal fortress lie above Traben-Trarbach on a bend in the Moselle River and were built at the end of the 17th century by order of the French Sun King, Louis XIV. The complex covered an area of 50 hectares and offered space for up to 12,000 soldiers and 3,000 horses. It was intended to serve as a supply base for the French Rhine Army and to control the central Rhineland. Only eleven years after construction began, following the Peace of Rijswijk in 1697, the French destroyed the fortress themselves in 1698 to avoid surrendering it to their opponents. Today, only a few remains of the once mighty fortress are visible. These include sections of the walls, casemates, cellar vaults, and defensive ditches. A large part of the ruins is overgrown by forest.

All that remains of the barracks, i.e. the accommodation buildings, are numerous vaulted cellars, which have collapsed in many places, creating a huge crater field.

Historically interesting, sure, but it's just a "dark hole."

A nice little climbing spot, but it can easily be bypassed by a small path.

Mining has shaped the village of Altlay and its residents and given the village its name Altlay. In local dialect, a lay is a roofing slate. Anyone who visits the narrow stream valleys around Altlay will not fail to notice striking evidence of mining here and there. Here, at every turn, you come across the remains of what was once a fairly extensive, predominantly small-scale roofing slate mining operation. Slate is still mined in Altlay today.
