Meteora

The Meteora is a rock formation in the regional unit of Trikala, in Thessaly, Greece, hosting one of the largest and most precipitously built complexes of Eastern Orthodox monasteries, second in importance only to Mount Athos. The six (of an original twenty-four) monasteries are built on immense natural pillars and hill-like rounded boulders that dominate the local area. Between the 13th and 14th centuries, the twenty-four monasteries were established atop the rocks. Meteora is located near the town of Kalabaka at the northwestern edge of the Plain of Thessaly near the Pineios river and Pindus Mountains. Meteora was added to the UNESCO World Heritage List in 1988 because of the outstanding architecture and beauty of the complex, in addition to its religious and artistic significance. The name means "lofty", "elevated", and is etymologically related to meteor. Geology Beside the Pindos Mountains, in the western region of Thessaly, these unique and enormous columns of rock rise precipitously from the ground. But their unusual form is not easy to explain geologically. They are not volcanic plugs of hard igneous rock typical elsewhere, but the rocks are composed of a mixture of sandstone and conglomerate.
