Summary

The account discusses the discovery of ancient underwater ruins off the coast of Mahabelli Purum, India, after the 2004 tsunami. Archaeologists had been investigating the area for two years prior to the tsunami. When the waters receded, they revealed structures believed to date back to the 7th century AD, including a famous Shore Temple. Local fishermen reported seeing multiple temples, but archaeologists confirmed only a few. Some researchers suggest the ruins could be much older, possibly dating back to 10,000 years ago. The impact of the encounter includes ongoing archaeological investigations and a shift in understanding the region's historical significance.

I have long regarded it because of its flood myths and fisherman sightings as a very likely place in which discoveries of underwater structures could be made.

Though some of the remains were badly damaged due to strong underwater current and swell and covered with thick aquatic growth, they could make out that they were part of a building complex.
