I saw this documentary on the history channel too.

It was amazing and the documentary divers themselves were convinced that those structures were man-made. One of them said that it was so eerie, there was just no way those structures were naturally formed. And they were the ones who discovered the carving of the headress. It looks like a spectacular location.

It made me want to learn diving even though I've never yet had the inclination.

Haribol!
