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
Mysteries of ancient civilizations excite the minds of hundreds of researchers around the world. Moreover, in the past history of peoples, has left us with dozens of buildings to explore. The oldest surviving man-made structures date back to the fourth Millennium BC.
In our current top ten contains the most ancient buildings on Earth . of interest, both to scientists and tourists, with pleasure visiting historical and architectural monuments.
10. Caucasian Dolmens, Russia.
These stone tombs are found on the territory of Krasnodar Krai, Adygea, Stavropol region and Abkhazia. Built most of these structures at the end of the third Millennium BC. Scientists know of about 3 thousand dolmens in the Caucasus. Unfortunately, many of them suffered greatly from vandals and natural impacts. Almost all dolmens access free, they are not fenced and, alas, were not guarded.
9. Keviczky tomb, Sweden.
This structure was built on the territory of modern Sweden more than 3 000 years ago. Long time local farmers used the ancient stones for their own needs, until in 1748’t started the scientific study of the object. Today Keviczky the tomb is open to visitors. Continue reading
Under barrow (underground) dolmen in Tolosa (lined with special masonry stones) with a dromos (an underground passage gallery). The unique megalithic complex. Possible ancient solar Observatory. And – complete collapse. Almost nothing has been preserved. At first the robbers is a long time. In our time the place of the mound needed for farming activities. The mound began to pull apart by bulldozers, to shred the roads. And then began the excavation. The sorry state of one of the most interesting megalithic structures of Russia made an attempt of computer 3D reconstruction of the megalith. Read more about the renovation, read the end of the article.
Location. Tuapse district, river valley Pshenaho.About a kilometer up the valley Pshenaho from the village of Anastasievka on the right orographic Bank is one of the most unique megalithic structures in the Caucasus. After some time, passing on a dirt road up the valley will see a fork. The road to the left leads through a Ford to the edge of the Apple orchard. Here is a small hill with several large oak trees, overgrown with grass and bushes (more than 150m). Continue reading
