Château Tour Saint Christophe is located on the Saint Emilion Grand Cru appellation and is at the border between the two villages of Saint-Émilion and Saint Christophe des Bardes. The shape of the property is a unique feature among the vineyards of Saint-Emilion. It is partly planted on narrow terraces where the vineyard is tended in tight rows grouped by five. This micro landscape extends into the slope overlooking the St Laurent valley.
The first cadastral map of the municipality from 1831 mentions a large plot of a few acres that eventually evolved into the terraces on the toponym Blanchon. The term fully evokes the terres blanches (white lands) of this part of Saint-Christophe-des-Bardes, a village generally best known for the abundance of red lands. The name Blanchon, or white lands, affirms a presence of a limestone plateau. An indentation of this plateau in Saint-Emilion is observable in the centre of the village, on the hill called Roc Blancan (white rocks) but where the terraces configuration is not as demonstrative as at Château Tour Saint Christophe.
