‘the only major architecture in the area not to be damaged by the December 26, 2004, Indian Ocean tsunami? The waves destroyed everything around the temple but did not touch the temple itself. It is a fact many witnesses acknowledged...
A forum called Oceanographers.net contains a post in which a scientist claims to have solved the mystery. After research conducted at the site, the scientist discovered that the site’s geographic location had a major role to play in the safety of the temple from the waves. He noted that the location is such where even the tidal waves, which hit other parts of the city, do not touch, and that a natural elevation in the rocks broke the chain of the waves. But in the end the scientist did give credit to those who built the temple at the place for choosing the site properly and after a careful study.
