Meteora is a cluster of vast sandstone dark rocks that rise out of Kalambaka,near the first hills of Pindos and Chassia. The monasteries of Meteora, which are built on top of some rocks, are currently the second most important monastic group in Greece, after Mouth Athos. Of the thirty monasteries only seven are currently operating, which, since 1988, have been in the list of UNESCO World heritage.
