Pharos at Alexandria

The Pharos at Alexandria was one of the Seven Wonders of the Ancient World. Construction on the 135 meter tall lighthouse began during the reign of King Ptolemy in 270 BC by the architect Sostratos but it wasn't until the sixth century AD when it became a Wonder, taking the place of the walls of Babylon.

The Pharos was believed to have been built in three stages with a square-shaped base, octagonal middle and cylindrical top with a spiral ramp leading up to the flame, and later fell into ruin between the 12th century and the time the Sultan Qait Bey constructed a fort over the lighthouse's remnants in the 15th century.
