Ansembourg Castle, Medieval castle in Helperknapp, Luxembourg
Ansembourg Castle is a stone fortress positioned on a rocky outcrop roughly 80 meters above the Eisch stream. The location provides expansive views across the surrounding valley and the forested landscape.
Written records first mention the site in 1135 under the lordship of Hubert d'Ansembourg. Major reconstructions during the Renaissance in the 16th century transformed its structure and appearance.
The castle houses a substantial library containing manuscripts and texts spanning multiple centuries. This collection reflects the family's long tradition of preserving knowledge and historical documents.
The castle remains a private residence and is closed to the public, as the count and countess family resides there. Visitors can view the exterior and appreciate the surroundings, but interior access is not permitted.
The castle gateway displays stonemason marks dating to 1565, left by craftsmen during reconstruction work. These markings offer a rare glimpse into the craftsmanship of Renaissance-era renovations.
