Greece is a country in south-eastern Europe with thousands of islands throughout the Aegean and Ionian seas. Prominent in ancient times, it is often called the origin of Western civilization. Athens, its capital, retains monuments including the 5th-century B.C. Acropolis citadel with the Parthenon temple. Greece is also recognised for its beaches, from the black sands of Santorini to the party resorts of Mykonos.
