The world's oldest lighthouse was built by Sostratus of
Cnidus around 270 BC.
It was a pyramid-shaped tower of white marble on the island
of Pharos (in Greek the word Pharos means lighthouse) off the coast of
Although no exact measurements of the lighthouse survived,
most eyewitness accounts are consistent regarding its size.
It was estimated to be almost 120 meters tall (between 103
and 108 meters) on a base of 30 by 30 meters.
It was one of the Seven Wonders of the World, a listing
designated by Antipater of Sidon in the second century BC.
The Pharos was described as made from white stone, most probably it had a marble façade.
The library was equipped with a hydraulic lift to raise fuel to the roof. Its signaling system,
probably a mirror reflecting a fire, could be seen over a radius of 50 kilometers into the Mediterranean. Within
its square base were about 300 rooms designed to house mechanics and operators; above were an octagonal storey and
a circular storey, topped by a lantern with a beacon, the exact workings of which are still a mystery.
At the top of the lighthouse, a statue of either Zeus or Poseidon stood.
