The Peloponnese (/ˈpɛləpəˌniːz/) or Peloponnesus (/ˌpɛləpəˈniːsəs/; Greek: Πελοπόννησος, Pelopónnēsos, is a peninsula and geographic region in southern Greece. It is separated from the central part of the country by the Gulf of Corinth. During the late Middle Ages and the Ottoman era, the peninsula was known as the Morea (Greek: Μωρέας), a name still in colloquial use in its demotic form (Μωριάς). The peninsula is divided among three administrative regions: most belongs to the Peloponnese region, with smaller parts belonging to the West Greece and Attica regions.
