Château La Tour Carnet is a genuine 12th-century medieval castle with a moat in Saint-Laurent-Médoc, recognized as a Fourth Growth in the 1855 Bordeaux classification. Named for a courageous equerry who distinguished himself alongside Lord Jean de Foy and earned the estate through valor, the château also hosted the renowned Renaissance writer Michel de Montaigne during the 16th century. The 73-hectare vineyard estate, owned by Bernard Magrez since 1999, produces acclaimed red and white Bordeaux blends. The property's exceptional terroir centers on the unique "Butte de la Tour Carnet," the Médoc's only clay-limestone mound, which imparts distinctive geological and visual character to this prestigious winery and historic landmark.
