What does Pharos mean?!

This word has puzzled me for too long ... At first I thought it was simply "Pharaohs" misspelt..
But then a few days ago, I typed it and hit the search button..
Turns out that it DOES HAVE A MEANING!!!

The website says:  

Pharos was a small island just off the coast of Alexandria. As the Egyptian coast is very flat and lacking in the kind of landmark used at the time for navigation, a marker of some sort at the mouth of the harbour was deemed necessary -
a function the Pharos was initially designed to serve.

The building was designed by Sostratus of Cnidus (Greek: Σώστρατος Κνίδιος - Sostratos
of Knidos or the Cnidian) in the 3rd century BC, after having been initiated by Satrap (governor) Ptolemy I of Egypt, Egypt's first Hellenistic ruler and a general of Alexander the Great.
The Pharos of Alexandria was a tower built in the 3rd century BC (between 285 and 247 BC) on the island of Pharos in Alexandria, Egypt to serve as that port's landmark, and later, its lighthouse.


With a height variously estimated at between 115 and 135 metres (383 - 440 ft) it was among the tallest man-made structures on Earth for many centuries, and was identified as one of the Seven Wonders of the World by classical writers.


It ceased operating and was largely destroyed as a result of an earthquake in 1375; some
of its remains were found on the floor of Alexandria's Eastern Harbour by divers in 1994. More of the remains have subsequently been revealed by satellite imaging .

The tower was made up of three stages: a lower square section with a central core, a middle octagonal section, and, at the top, a circular section. At its apex was positioned a mirror which reflected sunlight during the day; a fire was lit at night.

The design of minarets in many early Islamic mosques many centuries later followed a similar three-stage design to that of the Pharos, attesting to the building's broader architectural influence.

Legends tell of the light from the Pharos being used to burn enemy ships before they
could reach shore, however this is unlikely due to the relatively poor quality of optics and reflective technology in the period during which the building existed. Only slightly less impressive - and probably more accurate - is the claim that the light from the lighthouse could be seen up to 35 miles (56 km) from shore.


Pharos later became the etymological origin of the word 'lighthouse' in many Romance languages, such as French (phare), Italian (faro), Portuguese (farol), Spanish (faro), Romanian (far) and Greek (φάρος).
