Qasr al Bint, “Palace of the Daughter or Maiden,” is the largest tomb façade at Mada'in Saleh, with a height of 16 m. It lends its name to the group of adjacent tombs.
In the middle of the Jebel Ithlib is a natural slit that measures 40 m (131 feet), called the Siq, after a similar corridor at Petra.
The most photogenic and most iconic symbol of Mada’in Saleh is Qasr al-Farid, a single tomb carved into a small dome that stands alone in the open.
Area C is an outcrop in the southeastern part of Mada'in Saleh that contains numerous tombs, dating to 16-61 CE.
