Mada'in Saleh was the second largest city for the Nabataeans

Mada'in Saleh was the second largest city for the Nabataeans, namely people who settled throughout Arabia until the Jordan Valley until their kingdom was occupied by the Romans in 106 AD. Now, the city only remains in ruins.

The ruins left 130 ancient tombs and small pre-Islamic era altars, all made of stone walls. In this place tourists can witness the Nabatean art skills through carvings on the stone wall. The inscription is a remarkable relic because the Nabataeans did not leave much written history.
In contrast to Petra, which was the capital of the Nabatea tribe, which is now increasingly crowded with tourists, Mada’in Saleh is truly amazingly maintained. Maybe it's because this place is hidden in a lonely desert.
Thanks to its rich history, Mada'in Saleh was designated a UNESCO World Heritage Site in 2008, the first site in Saudi Arabia to receive this award.
