a peninsula in Greece, the southern part of the Balkan peninsula. It is connected with the mainland by the Isthmus of Corinth, which is cut by the Corinth Canal. Area, 21,500 sq km.
The Peloponnesus is washed by the waters of the Ionian and Aegean seas and their gulfs. Its shoreline is deeply indented, with many gulfs, bays, and peninsulas. Mountains predominate, composed primarily of Mesozoic and Paleogenic limestones, marbles, sandstones, conglomerates, and marls and schists. The chief mountain ranges, which have rocky limestone crests, are the Taiyetos, with elevations to 2,404 m (at Mount Ayios Ilias), and Parnon. In the central part is the Arcadian karst plateau, with karren, conical depressions, and poljes.
The Peloponnesus has a subtropical Mediterranean climate. Annual precipitation ranges from 400 mm in the east to 1,000 mm in the west; in summer there is drought. The peninsula’s vegetation is primarily scrub and evergreen (maquis) in the west and evergreen deciduous (xerophytic) in the east. On the western windward slopes are remnants of oak, fir, and pine forests. Much of the area is rocky wasteland. Olives, citrus and other fruits, tobacco, wheat, and corn are cultivated in the basins and valleys, and there are orchards. Livestock is raised, primarily sheep and goats. The cities of Sparta, Corinth, and Patras are located on the Peloponnesus, as are the ruins of Mycenae and Olympia.
