The Three Castles of Eguisheim are 11th-to-12th-century fortifications silhouetted against Schlossberg hill, dominating the Alsace plain from an altitude of 591 meters. The ensemble comprises Wahlenbourg (the oldest, reportedly connected to Pope Leo IX), Dagsbourg, and Weckmund, each originally featuring pink sandstone keeps that gradually fell to ruin from the 15th century onward. According to local tradition, these castles represent a source of fire, water, and gold, while their unique shadow patterns once served as a sundial for workers of the plain, with architectural and historical significance recognized across the Alsace Wine Route.
