19th-century explorers John L Stephens and Frederick Catherwood altered our view of the Maya civilisation and uncovered great wonders such as this El Castillo (Kukulkan) pyramid, Mexico. Stephens even bought the Mayan city of Copan for $50 with the mis-guided intention of moving it along the river to US museums. The Mayans were one of the greatest civilisations of all time, building incredible structures without the use of metal tools, horses or carts. Even with these constraints, their buildings are as large as, if not larger than, some of the astounding Egyptian wonders.

In the early 1800s a party of men headed by a Thomas Beale set out from Virginia to the Colorado Rocky Mountains where they discovered gold. After mining a fortune in gold ore they exchanged it for treasure, which they then buried in Virginia's Blue Ridge Mountains. Beale recorded the secret location of the treasure in three numerical codes that when decoded would reveal the treasures value, its location and to who it belonged. Then in 1897 Clayton Hart discovered the three coded papers and soon after found out that they could reveal a great treasure in a pamphlet that revealed a deciphered paper revealing its value. With the help of his brother George, Clayton spent the next 50 years trying to uncover the location of Beale's treasure. They went to great lengths to break the ciphers, including assistance from America's top code breakers and even the supernatural!

Historically the 'face of God' has been linked to the one of the greatest Catholic relics - the Veil of Veronica - a similar miraculous image, created on the day of Christ's crucifixion. When stumbling under the weight of the cross His brow was mopped by St Veronica - and an imprint of his face was left on her cloth. Throughout the middle ages this image was revered and worshipped by hundreds of thousands of pilgrims visiting Rome - and even created its own guild of artists, dedicated to selling reproductions of the image to pilgrims. But after the rebuilding of St Peter's basilica - designed as a new home for all the greatest Christian relics - suddenly and without explanation the veil disappeared from view was it lost, or even stolen? The Vatican claims to still have the veil but it is no longer on public view.
