Palace or Monastery?
Though the established view is that Sigiriya's summit was the site of Kasyapa's palace, some (including Dr Raja de Silva, Sri Lanka’s former archaeological commissioner) are not convinced. In particular the absence of stone bases, post holes, visible foundations for cross walls or window sashes, and a lack of lavatory facilities has caused doubt and provoked heated academic debate as to the purpose of the structures. For de Silva, this site was a vast Buddhist monastery, embracing both Theravada and Mahayana practices, and existing for many centuries before and after Kasyapa's rule. The summit was a sanctuary for meditation, containing kutis (cells) for monks and paved paths for Buddhist perambulation.
