"Last year's excavations at Vadnagar had thrown new light on ancient trade and commerce that was in existence at Vadnagar as well as the nature of the ancient city found here," the ASI stated in a release today.
The operation will begin under Madhulika Samanta, Superintending Archaeologist, ASI.
The earlier excavation was able to find links pointing to the relationship between Vadnagar and Europe through West Asia.
"The ASI had been able to get two C14 dates from excavated localities at Vadnagar, setting the antiquity of these findings to the first century CE. Encouraged by these findings, the ASI has decided to excavate the remains of Vadnagar extensively this year," the release added.
