Your world is filled with structures that have stood the test of time. That give character to the cities and landscapes in which they’re located. That are visited by millions of people each year. And that capture our wonder for the marvels of engineering innovation and progress.
But while structures such as the Giza pyramids, Brunelleschi’s dome, and the Brooklyn Bridge are visual spectacles in and of themselves, they are just as important for the way they were designed as for the way they look. These and other structural masterpieces were, first and foremost, novel creations born from the most progressive engineering concepts and tools of their day. They represent uniquely effective solutions to perplexing structural concerns. And they serve as landmark moments in the millennia-long history
Now, experience the engineering genius that makes these works possible with Understanding the World’s Greatest Structures: Science and Innovation from Antiquity to Modernity—a marvelous learning experience that takes you around the world and reveals the stories behind the most famous bridges, churches, skyscrapers, towers, and other structures from thousands of years of history. Delivered by award-winning Professor Stephen Continue reading
Very interesting archaeological wonder is located in southern Evia . this 25 famous huge constructions called Drakospita (‘dragon house’). They are always located on steep slopes, towering above the terrain and is built of huge limestone blocks with pyramidal roof: the opposite walls converge, and the boards stacked on top of each other, each of which protrudes over the lower. Among other architectural features – monolithic jambs and lintels and projecting stone shelves from the walls.
There are many theories that explain who, when, how and why they built the dragon dwelling. Some claim that this ancient sanctuary of Zeus, Hera or Hercules. Others believe that it could be guard posts or protective facilities, and even shelters for lumberjacks. Whatever the truth, their Grand size and method of construction constitute an amazing mystery!

Most impressive of all the dragon houses of Evia is the structure located on mount Ochi at a height of 1389 metres, just above the village of Karystos. The amazing thing is that they have not used any of the connecting material, and a huge plate decorated with a decorative carving and fit exactly to each other. Continue reading
In northwestern Yakutia in the Upper Vilyui river stretches difficult terrain with traces of some grandiose cataclysms: a continuous fall of the old forest, and scattered all around rubble stretching for hundreds of kilometers. On this terrain deep under the ground are unknown metal objects. Their presence is manifested on the surface only spots bizarre vegetation, and these spots are a great danger to people. The ancient name of the area – Eluu Cherkekh (“death Valley”).
Some mysterious objects in the area are found on the surface.
One of them is a small, slightly flattened metal arch, which has some metal chambers in which even in the bitter cold warm. In ancient times, some hunters spent the night in the cells, but then got sick really bad. If spent several nights in a row, then soon died.
The elders forbade the people to go there, and this place was forgotten. Another mysterious object discovered by a geologist in 1936, is a protruding from the earth smooth metal hemisphere with a very smooth edge.
Metal color – reddish, the wall thickness is about two centimeters.
Dug hemisphere slightly inclined, and it is possible to enter riding on reindeer. Continue reading
