The writings indicated that the structure consisted of 4 main sections. At the bottom was a platform filled with statues that are still being discovered by present-day divers off the coast of Alexandria. Some researchers believe that ships docked just off this platform as well.

On top of this platform stood a square structure measuring 18 m (60 ft) on each side and roughly 56 m (184 ft) tall. In the middle of this section is a shaft and stairwell used for transporting material and fuel up the Pharos Lighthouse, and for visitors as well. The third section was an eight-sided structure measuring roughly 27 m (90 ft) high. It also contained a similar transportation shaft in the middle.

On top of this was a circular tower that housed the fire (for use to alert ships during the night) and the great mirror (for use during the day). A statue of Poseidon stood on top this tower.

The Pharos Lighthouse was a true wonder in architecture and engineering, bearing similarities to modern skyscrapers. It measured up to a modern 40-story building. The Greeks were so impressed with it that they included it as one of the Seven Wonders of the Ancient World.

The mirror of the Pharos Lighthouse appeared to be quite famous in ancient times. Many people believed that the mirror was so smooth and powerful that it could be used to reflect the sun's rays onto invading ships and burn them. Another belief was that the mirror was so strong it could be used to observe and spy on competing city-states across the Mediterranean Sea, more than 100 miles away. However, it is highly unlikely that either of these stories are true.
