A place of great agricultural activity even back in Gallo-Roman times : from the Gallo-Roman VILLA RUSTICA to the « GRANGIA » in the Middle Ages which was to give the estate its name. Lagrange discovers an early winegrowing vocation thanks to the Templars who join together two domains : – The « maison noble de Lagrange de Monteil » to the West joins the « Tenure of Pellecalhus » (meaning « peeled stone ») to the East. In the present-day vineyard, the names of two vine plots bear witness to this era, « l’Hôpital » and « La Chapelle »; – Lagrange becomes the largest wine producing estate in the Médoc.
