The Holy Trinity Monastery (also known as Agia Triad) is an Eastern Orthodox monastery in central Greece, situated in the Peneas Valley northeast of the town of Kalambaka. It is situated at the top of a rocky precipice over 400 metres high and forms part of 24 monasteries which were originally built at Meteora, one of the oldest still existing of the Meteora monasteries (Meteora means "suspended in the air" in Greek). Six of the 24 monasteries are still active and open to visitors. The church was constructed between the fourteenth and fifteenth centuries and is included in the UNESCO list of World Heritage Sites titled Meteora. The monastery was featured in the 1981 James Bond film, For Your Eyes Only.
The Holy Monastery of St. Stephen is one of the most attainable as we don’t have to cope with innumerable stairs to reach it. The small single-nave church of St. Stephen was built in the middle of 16th and decorated in 1545 or a little later.
The Meteora is one of the largest and most important complexes of Eastern Orthodox monasteries in Greece, second only to Mount Athos. The six monasteries are built on natural sandstone rock pillars, at the northwestern edge of the Plain of Thessaly near the Pineios river and Pindus Mountains, in central Greece.
