Some of us have been lucky enough to see one or more of the Seven Wonders of the World. But historians and archaeologists are still on the hunt for some of the most renowned objects in history.
Even with today's incredible advances in technology, there are treasures all over the globe yet to be uncovered.
Here's a list of the Seven Undiscovered Wonders of the World:
THE SAN JOSE
According to Bob Cembrola, curator of maritime history at the U.S. Naval War College in Newport, R.I., the San Jose is "the Holy Grail of shipwrecks."
The Spanish galleon and its 600 men sank off the coast of Colombia in 1708 after being attacked by an English squadron.The size of the ship's treasure is a matter of debate but it could be worth up to $10 billion.
Colombia launched an expedition in 1994 only to find that the coordinates they had obtained led to nothing but mud. Some explorers claim they know the ship's location and Carla Rahn Phillips, author of "The Treasure of the San Jose," has attempted to pinpoint the ship with help from navigational experts. She plans to publish the coordinates next year.
GENGHIS KHAN'S TOMB
According to historical sources, the great warrior Genghis Khan died in northwestern China in 1227 but no one knows the exact location of his final resting place.
In 1237, a Chinese ambassador claimed to have seen the grave and a Chinese warrior named "Kirelgu" named the location in 1370 but the burial site has eluded explorers. While many local and foreign expeditions are in the works, no one has yet discovered the grave.
If the site is ever located, however, it is doubtful that it would bear treasure. The Mongols apparently did not believe the body needed material things after death and therefore were unlikely to have buried anything with Khan.
TOMB OF NEFERTITTI
This Egyptian Queen lived in the 14th century B.C. and was married to the pharaoh Akhenaten. Thanks to a recovered bust, Egyptologists know what she looked like but don't know how she died or where.
While some believe Nefertitti's mummy is one of 11 unearthed in the Valley of the Kings in 1898, others are convinced that her tomb has not yet been discovered.
THE AMBER ROOM
The Amber Room was a gift from King Frederick William I of Prussia given to Peter the Great in 1716. Its walls were constructed entirely of amber panels, mirrors and marble mosaics. It is considered one of the great masterpieces of Baroque art.
The Room was installed at the Russian imperial palace at Tsarskoye Selo but when the Nazies invaded Russia in 1941, they dismantled the structure and later restored it for display at a castle in Kaliningrad, Russia. In 1945, Russians invaded the city and the invaluable room was never glimpsed again.
A treasure hunter from the Czech Republic, Helmut Gaensal, believes the Room is boxed up and hidden in tunnels under the ruins of a German castle near the Czech border. He is waiting for permission to start digging...
THE HOLY GRAIL
No one is clear about what exactly the Holy Grail is. Medieval writers claim it was the cup that Jesus drank from at the Last Supper. In the twentieth century, it was often referred to as the jar that Mary Magdalene used to rub ointment on Christ's feet. It has also been associated with the possible child of Christ (as in the best-selling novel The Da Vinci Code).
The fact that the Grail may merely be a literary device has not discouraged historians and archaeologists from searching for it. The Italian medieval scholar, Alfredo Barbagallo, believes that it may be in the catacombs under the Basilica of St. Lawrence outside the Walls in Rome.Today, the existence and the meaning of the Grail remain a mystery...
THE BATTLE OF ANGHIAN
In 1503, Leonardo da Vinci spent 18 months painting a mural of the Battle of Anghiari in the great hall of the Palazzo Vecchio in Florence. Though unfinished, many of Da Vinci's contemporaries believed this mural to be his masterpiece. He painted it in the traditional fiesco technique but left his work, incomplete, in 1506.
Cosimo I de'Medici hired Giorgio Vasari to remodel the hall in the mid-1500s. Maurizio Seracini, an expert in using science to analyze art, is convinced that Vasari hid the Da Vinci mural behind one of his own. To penetrate Vasari's mural without damaging it, however, requires technology that does not yet exist.
AMELIA EARHART'S PLANE
On July 2, 1937, Amelia Earhart and her navigator were three-quarters through a flight around the globe when their Electra 10-E plane lost contact with a Coast Guard ship near New Guinea and was never seen or heard from again.
While some believe Earhart's plane simply ran out of gas, landed somewhere in the central Pacific and sank, no one has been able to detect any remains in that area.More than 30 theories swirl around the Earhart crash. Some believe she was a U.S. spy captured and killed by the Japanese while others think she reversed directions and crashed back at her point of departure in New Guinea.The truth is still up in the air...
