Discover the magnificent Château d'Harcourt, a remarkably preserved medieval fortress dating from the 12th-14th centuries, and explore France's oldest arboretum established in 1802. Walk through the castle's impressive defensive walls and double moat system, then wander among nearly 3,000 trees representing 500 species from around the world. Important: The domain is currently closed throughout 2025 for major renovation works. Please check the official website (harcourt-normandie.fr) for reopening dates. When open, the castle operates March through November and is closed on Tuesdays. Plan for 1.5 hours to fully enjoy both the historic fortress and the tranquil arboretum.
