The Great Pyramid of Giza stands on the northern edge of the Giza Plateau, located about 10 miles west of Cairo. It is composed of over 2 ½ million blocks of limestone, which weigh from 2 to 70 tons each.
It's base covers over 13 acres and its volume is around 90,000,000 cubic feet. You could build 30 Empire State buildings with its masonry. It is 454 feet high which is equivalent to a modern 48-story building. There are currently 203 courses or steps to its summit. Each of the four triangular sides slope upward from the base at an angle of 51 degrees 51 minutes and each side has an area of 5 1/2 acres. The joints between adjacent blocks fit together with optical precision and less than a fiftieth of an inch separates the blocks. The cement that was used is extremely fine and strong and defies chemical analysis. Today, with all our modern science and engineering, we would not be able to build a Great Pyramid of Giza. The Great Pyramid is thought to have been erected around 2600 BC during the reign of Khufu (Cheops). Next to the Great Pyramid stands 2 additional large pyramids. The slightly smaller one is attributed to Cheop's son and successor , Kephren. The other, still smaller, is attributed to Kephren’s successor, the grandson of Cheops, Mykerionos. To the south-east of the Great Pyramid lies the Sphinx. The total number of identified pyramids in Egypt is about 80.

The Colosseum - the greatest amphitheatre of the antiquity - was built in Rome, Italy, about 1920 years ago. It is considered an architectural and engineering wonder, and remains as a standing proof of both the grandeur and the cruelty of the Roman world. After the splendour of imperial times, the Colosseum was abandoned, and in turn it became a fortress for the medieval clans of the city, a source of building materials, a picturesque scenery for painters, a place of Christian worship. Today it is a challenge for the archaeologists and a scenario for events and shows. COLOSSEUM

It stretches across the mountains of northern China, winding north and northwest of Beijing. It is constructed of masonry, rocks and packed-earth. It was over 5,000 km (=10,000 Li) long. Its thickness ranged from about 4.5 to 9 meters (15 to 30 feet) and was up to 7.5 meters (25 feet) tat 5,000 km).

In Portugese, this iconic monument is known as Cristo Redentor. The original design of the Christ the Redeemer statue was born by a man named Oswald. He designed it to have a globe in one hand and stand over a pedestal symbolizing the world but the design was not agreed upon. Another proposal for a monument was prepared and made in 1921 by the archdiocese of Rio de Janeiro. He organized an event named Seman de Monumento ("Monument Week") in hopes of attracting donations, which were attained mainly by Brazilian Catholics who readily awaited a design decision for an effigy.
