No need for paint or wallpaper when you have mulitcolored layers of sandstone. The external appearance of the rock in this area is stunning on its own. What the Nabateans found when they cut into it added I'm sure to the mystique of the place. The patterns and colors are magical. Swirls of reds, yellows, and purples decorate the interiors of most of the tombs with designs that put any 1960's concert poster to shame.
