Discover Meteora, one of the world's great monuments and a UNESCO-protected site recognized as "A Preserved and Protected Monument of Humanity." As the second most important monastic center in Greece, Meteora has welcomed ascetics since the 11th century and flourished between the 13th and 14th centuries. Set beside the Pindos mountain range in western Thessaly, its unique and enormous rock columns rise dramatically from the ground. Formed from a mixture of sandstone and conglomerate, these extraordinary formations are as geologically distinctive as they are spiritually significant.
