Hidden within the Himalayas, 155ft from the ground, these man-made caves are one of the World's greatest archaeological mysteries. The astonishing number of caves, some dug into the cliffside, others tunnelled from above are thousands of years old but who built them and why remains a mystery.
Prehistoric spiral carving, Cornwall, England. Labyrinths and mazes have a history that can be traced back over 4000 years. The earliest examples are found carved on rocks in various parts of the world. Labyrinths have been a potent symbol in many cultures for thousands of years but mazes are of more recent origin, evolving from the earlier labyrinths around five hundred years ago
thought to be the oldest sundial in the world it is carved on a stone outside the tomb of Knoth in County Meath. The two holes in the center of the image probably held the gnomon (Object used to cast the shadow.)
At ground level, the ruins of Stonehenge appear somewhat random and chaotic, but a view from the air reveals the monument's circular order. The site started out modestly around 3100 B.C. as a wide ring of wood posts surrounded by a ditch and bank. The familiar enormous rock slabs, some brought from hundreds of miles away, were added to the interior over a period of about 1,500 years.
Silbury Hill, Avebury. The largest man-made mound in Europe, mysterious Silbury Hill compares in height and volume to the roughly contemporary Egyptian pyramids. Probably completed in around 2400 BC, it apparently contains no burial. Though clearly important in itself, its purpose and significance remain unknown. There is no access to the hill itself. Distance from Shaftesbury to Avebury is 42 miles More
The Dead sea Scrolls. Between 1947 and 1956 Qumran has been the most important archaeological site of the world . In this period a collection of 972 ancient texts in 11 different caves has been found. The majority of them are made of parchment or papyrus, mainly written in Hebrew and Aramaic and few in Greek. http://paolo-deadseascrolls.blogspot.com/2011/06/final-report.html
