Château d'Eyran is a historic wine estate located in Saint-Médard-d'Eyrans in Gironde, with origins tracing back to 1317. The property features a distinctive round tower from a 16th-century fortified structure, complemented by a main residence from the late 17th century flanked by two pavilions. Owned by the de Sèze family since 1796, this approximately twenty-hectare vineyard combines contemporary wine production with sustainable environmental practices, producing respected red and white wines available for tours and tastings.
