This week on Expedition Unknown heads to India as he searches for Dwarka, the sub-continent’s version of Atlantis.
The name comes from the Sanskrit word Dvāravatī that means the many-gated city and it is described in ancient texts as being surrounded by walls and having four main gates.
It was also said to have been built on submerged land and to have been one of the richest cities on Earth with walls studded with gems.
In 2001 the Indian government announced they had found some ruins in the Gulf of Khambhat but further analysis of the objects and wooden samples found proved inconclusive.
The sea levels in the area have risen around 100 meters in the last few thousand years so it makes smaller finds quite hard to pin down as being evidence of large scale human occupation.
Josh goes diving in the Arabian Sea as he and the team search for evidence of this mythical lost city.
Expedition Unknown airs on Wednesdays at 9:00 PM on Travel Channel.
