As one of the seven modern wonders of the world, Petra is Jordan's most famous tourist attraction. Once the capital of the Nabataeans, it was rediscovered in 1812 by the Swiss Johann Ludwig Burckhardt and in 1985 it was added to UNESCO's World Heritage List. After the trade routes along Petra had changed, the city was slowly abandoned. What remains are the ruins, which can still be seen today. When visiting Petra you can look for monuments such as Al Khazneh (the treasury) and Ad Deir (the monastery). A walk to the top of the mountains gives you a beautiful view over the valley where Petra is located. Near Petra is the town of Wadi Musa, where you will find several restaurants and entertainment facilities.
