Hagio Pneuma (Holy Spirit)

The Holy Spirit Rock or Holy Ghost Rock, also known as the Agion Pneuma in Greek, is a rock in the Meteora rock formation complex of Thessaly, Greece. It stands on the northern flank of the westward-opening valley in which Kastraki, Trikala is located. The southern flank is guarded, so to speak, by Surloti Rock. South of it a NE trending line of additional precipices separates Kastraki from the more urban Kalabaka, a municipal unit, and seat of, Meteora (municipality). Kastraki is a community of Kalabaka.

Holy Spirit Rock is long and thin, trending also to the NE. It is multi-partite with a characteristic peak like a tab in the center. Seen from the end, the rock appears as a tall triangle. Kastraki is located mainly off its west end, but some of the streets of Kastraki climb the base of the rock. The NE trending ridge is not to be confused with the one further south that separates Kastraki from Kalabaka. West of the valley the Pineios (Thessaly) River flows N-S. To the east the valley rises gradually into the Meteora massif, where a number of monasteries are ensconced on precipices, which they were long before the Ottomans or their Albanian peace-keepers were in Greece.
