One of the 17 regions (Spanish Cataluña, Catalan Catalunya) in the northeast of Spain with the four provinces Barcelona, Gerona, Lérida and Tarragona. It is located on the north-western edge of the Mediterranean Sea and covers 32,000 km². The area has an extremely eventful history: in the 6th century BC the Greeks came, then the Carthaginians and finally 200 BC the Romans. The wines from today's DO area Alella were already drunk by the Roman Caesars. The capital Barcelona was already in the antiquity an important trade port. In the 6th century A.D., the Alans and Visigoths arrived, from which the name is derived (Gotalonien = Gothenland). Then, in the 8th century, the Moors conquered the area. They were expelled by Emperor Charlemagne (742-814), who incorporated the area into his empire.
