     The oldest stone buildings in the world are the pyramids. They have stood for nearly 5000 years, and it

seems likely that they will continue to stand for thousands of years yet. The most famous of these are the

"Step" pyramid and the "Bent" pyramid.

     Some of the pyramids still look much as they must have done when they were built thousands of years

ago. Most of the damage (破坏) has been at the hands of men who were looking for treasure or, more often,

for stones to use in modern buildings. The dry climate of Egypt has helped to preserve the pyramids, and their

very shape has made them less likely to fall into ruin (废墟). These are good reasons why they can still be

seen today, but perhaps the most important is that they were planned to last forever.

     It is most likely that plans were made for the building of the pyramids because the plans of other large

works have fortunately been preserved. But, there are no writings or pictures to show us how the Egyptians

planned or built the pyramid themselves. As a result, we are only able to guess at the methods used.

However, one thing is certain: there must have been months of careful planning before they could begin to

build. The first thing they had to do was to choose a suitable place. You may think this would have been easy

with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules

had to be followed, and certain problems had to be overcome.

     The pyramid had to be on the west side of the Nile, the side on which the sun sets. This was for religious

reasons. The pyramid also had to stand well above tho level of the river to protect it against the regular floods.

The pyramid could not be too far from the Nile, however, as the stones to build it needed to be carried in boats

down the river to the nearest point. Water transport was, of course, much easier than land transport. The

builders also had to find a rock base which was not likely to crack under the great weight of the pyramid.

Finally, the pyramid had to be near the capital, or better still, near the king's palace so that he could visit it

easily and personally check the progress being made on the final resting place for his body.
