Could the fabled lost city of Atlantis have been located? Using satellite photography, ground-penetrating radar and underwater technology, The film, Finding Atlantis, was screened by the National Geographic Channel in the US and fronted by Professor Richard Freund, from Hartford University in Connecticut. Professor Freund explained how he led a pursuit to find the lost civilisation, believed by many to be an ancient Greek myth, by using deep-ground radar, digital mapping and satellite imagery. He contends that Atlantis, described by Plato in 360BC, in Spain's Donaña National Park, north of Cadiz, and was wiped out by a giant tsunami. Plato wrote it had been destroyed by a natural disaster in 9,000BC. Experts are now surveying marshlands in Spain to look for proof of the ancient city.

The theory that Atlantis is buried in the Spanish wetlands is the latest in a long line of suggested locations. In 2004, US ocean researchers said they were convinced they had found evidence of Atlantis off the coast of Cyprus. Others include various Mediterranean islands, Central America and even Antarctica. Professor Freund said that some of Atlantis's inhabitants had fled a tsunami to establish similar "memorial cities" which he had identified in central Spain.

His film company, Associated Producers of Canada, added: "Besides identifying the location of the city, they discovered a stele that may have stood at the entrance to the ancient civilisation. It records the long lost symbol of Atlantis." The film's claims however were dismissed as having no reliable basis in scientific fact and of misinterpreting partial results by an investigation by a team of distinguished Spanish scientists. Since 2005 they have been working on the site at a huge national park and bird sanctuary near Cadiz. If the team can match geological formations to Plato's descriptions and date artifacts back to the time of Atlantis, we may be closer to solving one of the world's greatest mysteries.

The lost tomb of Genghis Khan could be unearthed and destroyed at any time. Can engineer/explorer Albert Lin, equipped with cutting-edge technology, and just a handful of obscure clues from ancient texts, find and protect his burial site?

In Salem Witch Trial Conspiracy, join author Katherine Howe as she embarks on a historical journey to bring you the truth behind the world's most famous witch-hunt. Of the over one hundred people charged with witchcraft, five died in jail, 19 died on the gallows and one was crushed to death. Each of these deaths was the result of an overwhelming religious hysteria, and even to this date historians are uncovering more about what really occurred. One of the first victims was a British born ancestor of Katherine, who revisits the site of the trials to examine fascinating new research and delve into Salem's horrific past. By studying the sermons of the village's Puritan minister Samuel Parris, historians have deduced that a chilling plot could have been the cause of the frenzy that followed. Parris was at the very heart of Salem's terror, and it was the supposed possession of his own niece and daughter that led to the first arrest. From studying his hand-written notes, which have been preserved to this day, it seems he believed his ministry was under attack. But was his true enemy the devil, or his own employers?

1692, Salem, Massachusetts; 162 people are arrested on charges of witchcraft. Five die in jail, one is crushed to death and 19 die on the gallows. The Salem witch trials have long been regarded as the textbook example of what happens when people are overwhelmed by hysteria. Now, author and historian, Katherine Howe, returns to the site of her ancestor's execution to discover how the very latest research has unearthed a chilling possibility that the most famous witch trial in the English speaking world was actually the result of a cynical plot by Salem's embattled Puritan Minister: Samuel Parris.
