The superb vineyard of Marsac Seguineau covers 10 hectares in the heart of the Soussan commune. Since 2001, Chateau Marsac Séguineau and the neighbouring Chateau La Tour de Mons were acquired by the Credit Agricole Group (which also own the Pauillac Classified Growth, Ch. Grand Puy Ducasse) therefore sharing management and technical staff. Produced with the same care and attention as its neighbour.
