Petra is an remarkable city. It is a city in Jordan without houses made up of only temples and tombs which all have been hewn from the rocks. It is not easy to reach this city since its access is very narrow. The light from the afternoon sun gives the red sand stone a unique appearance. The city was supposedly founded by the Nabateans, hundreds of years before Christ. Erich Von Däniken detailled the mysterious site of Petra (ref Däniken) and thereby referred to the remarkable "obelisk mountain". The top of this mountain was carved and cut by at least 7 metres, resulting in two remarkably tapering pillars. Why was it so important to carve up a mountain here, in this inhospitable area?
