By Maremma one understands in the broader sense a landscape in central Italy, to which the entire southern one Tuscany and parts of the northern Lazio belong. Originally, this was a marshland associated with the Tyrrhenian Sea, which in Roman times was called "Maritima Regio". This is the origin of the Spanish term "Marisma" (marshy coastal land). In the narrow sense, however, the Maremma covers only the shallow, interrupted by the hills of the Monti dell'Uccellina coastal strip between the Gulf of Follonica, the rivers of the Bruna and the Ombrone and the lagoon of Orbetello on Monte Argentario. The area is called the "El Dorado" of viticulture and the most interesting development area of Tuscany.
