The historical landscape was a separate Greek royal house in ancient times and became a Roman province from 148 BC. Here is Dodona, the most important ancient Greek oracle site after Delphi. Today the area belongs to Greece and partly also to Albania. But today only the southern Greek part is called Epirus. The smallest, least populated and roughest Greek region stretches in the west of Greece along the coast of the Ionian Sea in the south to the Ceraunian Mountains in the north. The highest elevation is the mountain Smolikas with 2.637 meters. Only one fifth of Epirus is not mountainous and the soil is very calcareous. In the west the mountains drop down to the coast of the Ionian Sea. The two wine-growing areas are Zitsa, to the west of the capital Ioannina, classified as POP, and Metsovo, not classified, to the east of the capital. Close to the coast are the Ionian Islands.
