One of the Seven Wonders of the World and the most famous lighthouse in antiquity, built on the island of Pharos in the harbor of Alexandria. It was a technological triumph and is the archetype of all lighthouses since. Built by Sostratus of Cnidus for Ptolemy II of Egypt in c 280 BC, it is said to have been more than 350 feet (110 m) high. The lighthouse was surmounted by a huge statue, probably representing either Alexander the Great or Ptolemy I Soter. Pharos appeared in the list of wonders in the 6th century AD and it was known to still be standing in the 12th century. By 1477, it was in ruins.
