Aquitaine is one of the most varied regions of France. Around the Gironde estuary, the region is low-lying land, and one of the most famous wine-producing areas in France. The highlight here is the picturesque town of Saint-Émilion. Bordeaux, the capital city, has many fine buildings in the old city, such as the unique eighteenth-century theatre. North of Bordeaux, to the west of the Gironde estuary, lies the area of Médoc, the most prestigious of the region’s wine-producing areas.
