Historical Mysteries that might never be solved

Camelot, the Knights of the Round Table, the Wizard Merlin, Legendary Sword Excalibur and its mythical wielder King Arthur. Despite all the stories, Archaeologists haven't found any confirmed proof that King Arthur actually existed and it is unlikely that we will ever know for sure.

Jack the Ripper, an infamous serial killer in 1888 killed at least five woman in London, mutilating their bodies. A number of letters were sent to the police, taunting officers to find the Ripper. Needless to say, the Ripper was never found.

On Nov. 22, 1963, President John F. Kennedy was shot in Dallas by Lee Harvey Oswald (although some speculate that he wasn't the only shooter). On Nov. 24, 1963, before Oswald could stand trial, Oswald was fatally shot by nightclub owner Jack Ruby. Ruby died of lung cancer on Jan. 3, 1967.

For more than two centuries, stories have circulated that Oak Island, located off Nova Scotia, Canada, held a money pit of buried treasure supposedly left by the pirate Capt. William Kidd (1645-1701). Over that time, numerous expeditions costing millions of dollars have traveled to the island searching for the lost treasure, to no avail.

In 587 B.C., a Babylonian army, under King Nebuchadnezzar II, conquered Jerusalem, sacking the city and destroying the First Temple, a building used by the Jewish people to worship god. The First Temple contained the Ark of the Covenant, which carried tablets recording the 10 Commandments. The fate of the ark is unclear.

Although December 25 is celebrated as the birth of Jesus, he likely wasn't born on this day. Ancient records suggest that early Christians were never able to agree on a date when Jesus was born and even today many Orthodox Christians celebrate Jesus' birthday as being on Jan. 6 or 7. In the end, it is unlikely that the date of Jesus' birth will ever be known

Writing in the fourth century B.C., the Greek philosopher Plato told a story of a land named Atlantis that existed in the Atlantic Ocean and supposedly conquered much of Europe and Africa in prehistoric times. In the story, the prehistoric Athenians strike back against Atlantis in a conflict that ends with Atlantis vanishing beneath the waves.

The Holy Grail, the cup that Jesus drank from at his last supper with his disciples before his crucifixion, has never been found and almost certainly never will be.
