Archeologists say the remnants found four years ago are more than 200 years old.

And now we know some pretty interesting details.

Researchers still don't know for sure why the ship sank — whether it was by accident or deliberately used for landfill to expand the island of Manhattan as we know it today.
Two researchers tell The New York Times they think it was probably the latter — pointing out sawed-off beams that could indicate it was purposely sunk.
But the scientists do know, based on artifacts taken from the ship, it was used for carrying Dutch passengers and cargo over shallow water. (Via WNYW)
And LiveScience cites previous studies that said it might have even traveled as far as the Caribbean for trading — where scientists say it was affected by a form of "shipworm" that might have contributed to its demise.
Archeologists have also found many other artifacts while excavating Ground Zero. They say discovering the ship and its origins helped them date those other artifacts.
