Fodor's Expert Review Vallée de la Pétrusse
Luxembourg City
Park (National/State/Provincial)
Full of willows, cherry trees, and bluffs, this broad park lies in the canyon of the Pétrusse river. Near the high Viaduc, you'll see the Chapelle Saint-Quirin built into the rocks. The cave is said to have been carved by the Celts; it is known to have housed a chapel since at least the 4th century.
