Mysterious Places in the World

Bermuda Triangle

1. Tales of lost mariners and disappeared ships, crashed aircraft and even vanishing humans, have been emerging from the waters of the Bermuda Triangle for centuries.
2. The vast area of more than half a million square miles is also known as the Devil’s Triangle, and theories as to why so many travellers fall foul of its clutches abound.
3. Some say there are magnetic anomalies that throw compasses off course, others that tropical cyclones are to blame, and some say there’s simply no mystery at all! Today, visiting the area can be much more pleasant than you might think, with the sun-splashed islands of Turks and Caicos beckoning in the south and the coves of Bermuda in the north.

Great Pyramid of Giza

Timeline and map of the Great Pyramid of Giza and the other Wonders of the Ancient World

1. The Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza pyramid complex bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact.
2. Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10 to 20-year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. 
3. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

Stonehenge

1. Stonehenge is a prehistoric monument in Wiltshire, England, 2 miles (3 km) west of Amesbury. It consists of a ring of standing stones, with each standing stone around 13 feet (4.0 m) high, 7 feet (2.1 m) wide and weighing around 25 tons.
2. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds.
