## The Golden Ratio was used in designing the Egyptian Pyramids.

The Egyptians thought that the golden ratio was sacred and it was very important in their religion. They used the golden ratio when building the Great Pyramids and the layout of the three great pyramids of Giza use the curve of the Golden Ratio that is predominant in a nautilus shell. The stone blocks used to construct the pyramids were crafted into the Golden Ratio.

The Golden Ratio was also used in constructing The Parthenon.

The Greek sculptor Phidias widely used the Golden Ratio in his works of sculpture. The exterior dimensions of the Parthenon in Athens, built in about 440BC, form a perfect golden rectangle. Ancient Greeks believed that structures designed with this ratio are more pleasing to the eye. The length and height of the building, the spacing between the columns and the pitch of the roof are all controlled by this ratio.

The Taj Mahal in India was also constructed using the Golden Ratio.

The main building of the Taj Mahal was designed using the Golden Ratio. This is why it looks so perfect. The rectangles that served as the basic outline for the exterior of the building were all in the Golden Proportion.

The Pentagon is another example of the Golden Ratio used in artchitechture.

In modern times the golden ratio has held a special interest in the mind of humans. It has been used in ancient architecture and now it is also being used in modern architecture as seen in the pitcure of The Pentagon below.
