Epirus (Greek: Ήπειρος, Ípiros), formally the Epirus Periphery (Περιφέρεια Ηπείρου, Periféria Ipírou), is a geographical department and administrative region (periphery) in northwestern Greece.[1] It borders the peripheries of West Macedonia and Thessaly to the east, West Greece to the south, the Ionian Sea and the Ionian Islands to the west and the country of Albania to the north. The province has an area of about 9,200 km² (3,551 square miles). It is part of the wider historical region of Epirus, which overlaps modern Albania and Greece but mostly lies in modern Greek territory.
