Underwater city of Khambhat

Marine archeology in the Gulf of Khambhat - earlier known as Gulf of Cambay - centers around controversial findings made in December 2000 by the National Institute of Ocean Technology (NIOT). The structures and artifacts discovered by NIOT are the subject of contention. The major disputes surrounding the Gulf of Khambhat Cultural Complex (GKCC) are claims about the existence of submerged city-like structures, the difficulty associating dated artifacts with the site itself, and disputes about whether stone artifacts recovered at the site are actually geofacts or artifacts.
