Among the Sgiriya Rock creations, the first is the cave design. Some of the caves are said to be more than 5000 years old. However, many drip-lined caves dating back more than two or three hundred years to the King Kashyapa period have also been found. In particular, dripstones can be seen only in the caves to the west of Sigiriya rock. The most famous name of this cave is the Naipena Cave (Cobra Hood Cave).
