A shipwreck believed to date back to Roman times was found at the bottom of Montenegro's Boka Kotorska bay, officials said on Tuesday.
"We believe we have found the wreckage of a ship that could have been used to transport goods," Montenegro's regional Cultural Heritage Preservation Institute said in a statement.
Officials refused to reveal the location of the shipwreck until the area was fully secured.
The wreckage was found by the crew of the US explorer ship Hercules. Since May, the crew and the ship have been assisting Montenegrin archaeologists to map and discover underwater findings.
The Romans were present in the waters off what is now Montenegro from the year 9 AD till the 5th and 6th centuries AD, before Slavic people inhabited the area.
