For over 2000 years, Kelaniya Temple has stood at the edge of an invisible world of serpent kings, subterranean kingdoms and rival armies. A jewelled throne once lay at the centre of a violent family feud between two Naga rulers until the Buddha intervened to stop the coming slaughter. Portuguese forces later reduced the ancient temple to ruins but its oldest legend endured. Even now, the river and earth murals preserve traces of that forgotten prehistoric empire.
