I suggest everyone to watch a documentary film about the ancient, great city Peter (Accent on the first syllable).
Ancient City of Petra(That means "rock") — the capital of Idumea (Edom), later the capital of the Nabataean kingdom. Located on the territory of today's Jordan, at an altitude of over 900 meters above sea level and 660 meters above the surrounding area, Arava, in the narrow Siq canyon. Passage in the valley — a valley, located on the north and the south. From the east and the west, cut off by sheer cliffs, thus forming a natural wall of up to 60 m in height.
Petra is a regal rock of red sandstone, which cut down the extraordinary porticos, outwardly similar to the Roman architecture. Monks are often constructed their homes in caves, and they always look amazing. Peter stands out from these buildings that is a true work of architectural art. The impression of the unusual color of the facade increases the rocks: an intricate way he poured all the shades of red, pink and orange.
