Petra
About this place
This fountain is located in Wadi al-Farasa. A huge lion is carved in the sandstone rock, on the way to the High Place. The carved channel above the lion's head received water from 'Ayn Braq", along the mountain slope on the way to Tayyiba high above Petra. The water collected in a basin and flowed to to a large cistern at the foot of the mountain.

Inhabited since prehistoric times, this Nabataean caravan-city, situated between the Red Sea and the Dead Sea, was an important crossroads between Arabia, Egypt and Syria-Phoenicia. Petra is half-built, half-carved into the rock, and is surrounded by mountains riddled with passages and gorges. It is one of the world's most famous archaeological sites, where ancient Eastern traditions blend with Hellenistic architecture.
