Building the tallest building in the world is not only a very hard architectural challenge, but hides many deep meanings, related to culture and country where it’s built.
The Great Pyramid of Cheope, the oldest of the Seven Wonders of the Ancient World, is not only a tomb of the Egyptian pharaon, but was the tallest building in the world for over 3800 years; by the way, for the primitive building techniques, the construction has proceeded very slowly, and totally it took over 20 years to be built.

Today the tallest building in the world is the Burj Khalifa, a skyscraper in Dubai: construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. With the modern techniques (bulldozers, new materials…) is possible to create a 828 mt. tall building in a very fast period, only 5 years.
