High in the Vosges Mountains of northeastern France lies a relic of history that sparks curiosity and wonder: the Château d’Engelbourg. Once a proud medieval fortress guarding the strategic routes near Thann, its ruins now captivate visitors with a mix of history, mystery, and breathtaking views.
The highlight of this site? A curious feature known as the “Witch’s Eye”, a large stone ring that has become synonymous with the castle. Whether you’re a history buff, a lover of legends, or simply looking for a picturesque spot to explore, Château d’Engelbourg has plenty to offer.
From Fortress to Ruins
Built in the early 13th century by Count Frederick II of Ferrette, the Château d’Engelbourg was strategically positioned to monitor the valley and protect trade routes through the Vosges Mountains. It was part of a network of fortifications that symbolized power and control over the region.
The castle saw its share of battles and sieges during the Middle Ages. However, its fate was sealed in 1673 when Louis XIV’s military engineer, Vauban, ordered its destruction to prevent its use by enemies. The resulting explosion reduced the castle to ruins—but it also created the iconic “Witch’s Eye,” a massive circular piece of masonry that tumbled and landed upright, resembling a stone monocle gazing out over the valley.
Today, the Château d’Engelbourg is not only a historical site but also a cultural landmark, drawing visitors with its rich past and dramatic landscape.
