Elis

Elis or Ilia (Ηλεία, Ileia) is a historic region in the western part of the Peloponnese peninsula of Greece. It is administered as a regional unit of the modern region of Western Greece. Its capital is Pyrgos. Until 2011 it was Elis Prefecture, covering the same territory. The modern regional unit is nearly coterminous with the ancient Elis of the classical period. Here lie the ancient ruins of cities of Elis, Epitalion and Olympia, known for the ancient Olympic Games which started in 776 BC. The northernmost point of Elis is 38° 06'N, the westernmost is 22° 12′E, the southernmost is 37° 18′N, and the easternmost is 21° 54′E. The length from north to south is , and from east-to-west is around . The modern regional unit is not completely congruent with ancient Elis: Lampeia belonged to ancient Arcadia, and Kalogria is now part of Achaea. The longest river is the Alfeios. Other rivers are the Erymanthos, Pineios and Neda. Alfeios, Pineios and Neda flow into the Ionian Sea in Elis. Less than 1% of the prefecture is open water, most of it found in artificial reservoirs and dams, in the north and east. The Pineios Dam supplies water for Northern Elis. The water is not safe for drinking, because it contains some contaminants. A second, smaller reservoir in the river Alfeios near Olympia and Krestena supplies water to Pyrgos. The eastern part of the regional unit is forested, with mostly pine trees in the south. There are forest preserves in Foloi and the mountain ranges of Eastern Elis. In the north is the Strofylia forest which has pine trees. Mountain ranges include Movri (around 720 m or 2,400 ft), Divri (around 1500 m), Minthe (around 1100 m), and more. About one-third of the land is fertile; the rest is mountainous and not suitable for crops. Swamplands used to cover 1–1.5% of the region, especially in the Samiko area. Most of them have been drained for agricultural purposes; only 10 km2 (4 sq miles) has been kept and is now protected. Here lie the ancient ruins of Elis, Epitalion and Olympia, known for the ancient Olympic Games which started in 776 BC.
