The Sigiriya Damsels
The Sigiriya Frescoes (alternately known as the Sigiriya Ladies or Sigiriya Damsels) are a set of ancient frescoes located in a small cave about 100 meters up the towering Sigiriya rock. They're considered one of the top attractions of Sigiriya itself and are the most important (and in fact only) non-religious paintings which have survived from antiquity in Sri Lanka.
Apparently, the ostentatious King Kaspaya decided on Sigiriya as his palace in the 1st century BC and, as a testament to his grandeur, actually white-washed the entire rock and added a 40-meter wide band of paintings decorating the entire western side of the Rock. After more than a millennium exposed to the elements, the nineteen Sigiriya Frescoes are all that we have left of this once magnificent palatial complex.
