Lighthouse of Alexandria
Lighthouse of Alexandria also called Pharos of Alexandria, one of the Old 7 Wonders of the World and the most famous lighthouse in antiquity. It was a technological triumph and is the archetype of all lighthouses since. Built by Sostratus of Cnidus, perhaps for Ptolemy I Soter, it was finished during the reign of Soter’s son Ptolemy II of Egypt in about 280 BCE.
The lighthouse stood on the island of Pharos in the harbor of Alexandria and is said to have been more than 350 feet (110 meters) high; the only taller man-made structures at the time would have been the pyramids of Giza. Much of what is known about the structure of the lighthouse comes from a 1909 work by Hermann Thiersch, Pharos, antike, Islam und Occident.
According to the ancient sources consulted by Thiersch, the lighthouse was built in three stages, all sloping slightly inward; the lowest was square, the next octagonal, and the top cylindrical. A broad spiral ramp led to the top, where a fire burned at night.
Some descriptions report that the lighthouse was surmounted by a huge statue, possibly representing either Alexander the Great or Ptolemy I Soter in the form of the sun god Helios. Though it was well known earlier, the lighthouse does not appear in any list of wonders until the 6th century CE (the earliest list gives the walls of Babylon instead).
The lighthouse of Alexandria. was still standing in the 12th century
In the Middle Ages sultan, Ahmed ibn Toulon replaced the beacon with a small mosque. The lighthouse was still standing in the 12th century, but by 1477 the Mamlūk sultan Qāʾit Bāy was able to build a fort from its ruins.
Archaeologist Jean-Yves Empereur’s discovery from The lighthouse of Alexandria.
In 1994 archaeologist Jean-Yves Empereur, founder of the Centre for Alexandrian Studies (Centre d’Etudes Alexandrines), made an exciting find in the waters off Pharos Island.
He had been called in by the Egyptian government to map anything of archaeological significance in this underwater area before a concrete breakwater was erected over the site. He mapped the location of hundreds of huge masonry blocks; at least some of these blocks are believed to have fallen into the sea when the lighthouse was destroyed by an earthquake in the 1300s.
A large amount of statuary was also discovered, including a colossal statue of a king dating to the 3rd century BCE that was thought to represent Ptolemy II. A companion statue of a queen as Isis had been discovered nearby in the 1960s, and these statues representing the deified Ptolemy and his wife, Arsinoe, are thought to have been placed just below the lighthouse, facing the entrance to the harbor.
Based upon these finds, the Egyptian government abandoned the idea of a breakwater and planned instead an underwater park where divers could view the many statues, stone sphinxes, and remains of the lighthouse of Alexandria.
