Kashyapa the Rebel King
King Kashyapa (also known as Kasyapa I or Kassapa), was the eldest son of King Dhatusena, by a palace concubine. As legend goes, King Dhatusena was overthrown and walled in, alive by Kashyapa in 473 AD. Mogallana, Dhatusena’s son by the true queen fled to India, vowing revenge. Fearing retribution, Kashyapa built this impregnable fortress at Sigiriya and sought salvation from his brother’s vengeance
When the invasion finally came in 491, Kashyapa rode out to battle in his war elephant. In an attempt to out-flank his half-brother, Kashyapa took a wrong turn, where his elephant got stuck in the mud. His soldiers, thinking Kassapa was retreating fled, abandoning him, and Kassapa took his own life.
Sigiriya later became a monastic refuge, but eventually fell into disrepair.
