AKIPRESS.COM - A Greek merchant ship dating back more than 2,400 years has been found lying on its side off the Bulgarian coast, BBC reports.

The 23m (75ft) wreck, found in the Black Sea by an Anglo-Bulgarian team, is being hailed as officially the world's oldest known intact shipwreck.

The researchers were stunned to find the merchant vessel closely resembled in design a ship that decorated ancient Greek wine vases.

The rudder, rowing benches and even the contents of its hold remain intact.
