<P> The Lighthouse of Alexandria , sometimes called the Pharos of Alexandria ( / ˈfɛərɒs / ; Ancient Greek : ὁ Φάρος τῆς Ἀλεξανδρείας , contemporary Koine Greek pronunciation : ( ho phá. ros teːs a. lek. sandréːaːs ) ) , was a lighthouse built by the Ptolemaic Kingdom between 280 and 247 BC which has been estimated to be 100 metres in overall height . One of the Seven Wonders of the Ancient World , for many centuries it was one of the tallest man - made structures in the world . Badly damaged by three earthquakes between AD 956 and 1323 , it then became an abandoned ruin . It was the third longest surviving ancient wonder ( after the Mausoleum at Halicarnassus and the extant Great Pyramid of Giza ) until 1480 , when the last of its remnant stones were used to build the Citadel of Qaitbay on the site . In 1994 , French archaeologists discovered some remains of the lighthouse on the floor of Alexandria 's Eastern Harbour . The Ministry of State of Antiquities in Egypt has planned , as of late 2015 , to turn submerged ruins of ancient Alexandria , including those of the Pharos , into an underwater museum . </P>
