Colpach Castle

Colpach Castle, known locally as Schlass Kolpech, is situated in Colpach-Bas near Ell in western Luxembourg. Originally constructed as a small medieval stronghold surrounded by a moat at the beginning of the 14th century, the structure was first documented in 1303. Over the centuries, it underwent significant transformation, particularly in 1747 when the Pforzheim family filled in the moat and adapted the fortress into a modest manor house. In the late 19th century, Baron Edouard de Marches developed the extensive gardens, creating curved pathways, ornamental plantings, and a lake with an island that remain visible today.

The castle gained considerable historical prominence after industrialist Émile Mayrisch purchased the estate in 1917. He commissioned architect Sosthène Weis to enlarge and modify the building, giving it a simple yet elegant style. Between the two world wars, Mayrisch and his wife Aline turned the castle into a vibrant cultural hub, hosting distinguished guests such as composer Franz Liszt, writer André Gide, and politician Walther Rathenau. Following Aline Mayrisch's death in 1947, she bequeathed the property to the Red Cross to serve as a convalescent home, ensuring its continued utility for public welfare.

Currently, Colpach Castle operates as a 60-bed medical facility dedicated to post-oncological and physical rehabilitation under the management of the Red Cross via the Fondation Emile Mayrisch. The site was officially listed as a national monument in 2002, recognizing its architectural and historical value. While the interior functions as a medical center, the surrounding park remains open to visitors year-round and is notably accessible for handicapped individuals, preserving the scenic landscape established during the 19th century.
