326 JO - Petra (1985)

Brief Description

"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."

佩特拉
"佩 特拉城位于红海和死海之间，它的历史可以追溯到史前时代，最初是由纳米泰人沙漠商队建立的，它位于阿拉伯、埃及、叙利亚腓尼基之间的交通要塞。佩特拉城一 半向外突出，一半嵌入岩石中，周围群山环绕，山中道路蜿蜒，峡谷深深，是世界上最著名的考古遗址之一。古希腊建筑与古代东方传统在这里交汇相融。"
