Architecture is the art which makes buildings beautiful to look at as well as useful A man who designs buildings and makes the plans for them is called an architect. He has to think not only of what he wants the building to look like when it is finished, but also what it is to be used for. He must not forget the sort of material to be used in the building, this may be stone, brick or steel and concrete.

There have been many different styles or kinds of architecture is the past and there are many different styles today in different parts of the world.

The oldest monuments which are met within architecture are the colossal pyramids of Egypt most of which were constructed about 6000 years ago. The pyramids are large triangular buildings which were placed over the tombs of Egyptian kings.

Ancient Egypt's rulers thought chiefly of building for eternity. This purpose drove earlier pharaohs to build massive stone pyramids in which their dead bodies would be stored and preserved against decay, until that time when, according to their religion their souls would once more return to their bodies.

The best known of the pyramids are a group of three built at Giza south of Cairo. The Great Pyramid of Khufu is estimated to weigh 5,750,000 tons, it is the heaviest structure ever built for all its size - 760 feet square and 482 feet high - it contains only small rooms, two of which are burial chambers.

The room for the Pharaon is only 34 feet, 6 inches long, 17 feet wide, and 19 feet high; the other two are smaller. How the Pyramid was constructed is still largely a mystery. Without crane, block and tackle, wheel or wagon, nearly six million tons of stone were quarried, carried by raft across the Nile and put into place. Large blocks of stone were transported over long distances by land and water, and place into position with the of the most primitive equipment. That was done by slaves working for thirty or forty years. The country was rich in hard and durable stone, but poor in timber and metal, so that the main material used for construction was granite, and this was the reason for the durability of Pyramids.
