penthesileas:Art and Architecture - Petra, Jordan. Possibly established in 312 BCE as the capital city of the Nabataeans, it was rapidly built in a Hellenistic style in the 1st century BCE. The city eventually came under Roman rule and began to decline rapidly. The last inhabitants abandoned the city in 663 CE and the site remained a curiosity in the Middle Ages. It remained unknown to the Western world until 1812. -- source link
