It is estimated that over 3Million Undiscovered Wrecks are spread across ocean floors around the globe.
Over
the centuries, entire cities have been swallowed by the waves, and
thousands of ships have perished at sea. Nowadays their remains
constitute a precious archaeological heritage of utmost cultural
importance. Many sites have not been touched for centuries or even
millennia and biological material is often much better preserved than
when on land due to the lack of oxygen, which would have facilitated its
deterioration. This makes these sites unique.
Famous vessels include among others:
- The Armada of Philip II of Spain
- The Fleet of Kublai Khan
- The Ships of Christopher Columbus
- The Spanish galleons that connected America to Spain
The
remains of countless ancient buildings are now submerged. While Atlantis remains a legend, archaeological underwater sites the
size of Pompeii have been discovered. Famous sites include:
- The bay of Alexandria, with remnants of the lighthouse and Cleopatra’s palace
- Parts of the ancient Carthage, now submerged
- Parts of the world heritage site at Mahabalipuram, India
- The site of Dwarka, India
- Jamaica’s Port Royal, destroyed by an earthquake in 1692
Underwater Cultural Heritage also encompasses artefacts preserved in flooded caves.
Such sites include:
- Cenotes in Mexico (Chichen Itza)
- Neolithic rock art caves in the Black Sea
Some
of
the world's best preserved prehistoric landscapes survive at the
bottom of the North Sea. Dating from approx. 50,000-60,000 years ago,
they also encompass Neanderthal hunters' kill and camp sites. It is
estimated that hundreds or even thousands of square miles of
post-ice-age, prehistoric landscapes may in this way have survived.
