Attica is a peninsula, at the southernmost point of central Greece, sticking out into the Aegean Sea. The Attica region is, in an official sense, the peninsula with the island section. Mainland Attica is correspondent with the Athens metropolitan area. Its population is about 4 million people. The region is physically divided from Boeotia by the 16 km (9.9 mi)-long Kithairon mountain range, to the north. The peninsula is separated by mountains into the plains of Pedia, Mesogeia, and Thriasia. The mountains include Hymettus, the eastern portion of Geraneia, Parnitha, Aigaleo and the Penteli mountains. To the north, it is bordered by the Boeotian plain and to the west it is bordered by Corinth. The Saronic Gulf lies to the south and the island of Euboea lies off the north coast. Athens' first and only large reservoir was opened in the 1920s called Lake Marathon Since that time, it has been Attica's largest lake. Forests cover the area around Parnitha, around Hymettus and into the northeast and the north in the hills and the mountains, except for the mountaintops, but the mountains to the west and the south are grassy, desolate or forested.
The great history of Greece is connected with Athens, where the notion of democracy was invented.
