Researchers believe that they have identified the wreck of Christopher Columbus' flagship, the Santa Maria, more than 520 years after it ran aground off the northern coast of Haiti, according to a published report. 

"All the geographical, underwater topography and archaeological evidence strongly suggests that this wreck is Columbus’ famous flagship, the Santa Maria," researcher Barry Clifford told The Independent newspaper. 

The wreck had already been discovered and photographed in 2003, but it is not until recently that researchers have considered the possibility that it might be the largest of the three ships Columbus sailed from Spain in 1492.
