Where? L-9650 Esch-sur-Sûre
Set in a valley of the Sûre river in the Éislek, the village of Esch-sur-Sûre is situated in a meander of the river at the foot of the ruins of the oldest castle in Luxembourg. The ruins of the feudal castle, which is freely accessible, offer a wonderful view of the village and its narrow streets that have barely changed since the Middle Ages. Western of the village lies the Upper-Sûre Lake, which is a popular attraction in summer.
