Lighthouse of Alexandria

The lighthouse of Alexandria or the pharos of Alexandria, Greek was a tower built in the 3rd century BC between 285 and 247 BC on the island of pharos in Alexandria, Egypt to serve up as that port’s landmark and later, its lighthouse.

With a height variously predictable at between 115 -150 meters (377 - 492 ft) it was amongst the tallest man-made structures on Earth for many centuries, and was recognized as one of the Seven Wonders of the World by Antipater of Sidon. It may have been the third tallest building after the two Great Pyramids (of Khufu and Khafra) for its whole life. Some scholars estimate a much taller height more than 180 meters that would make the tower the tallest building up to the 14th century.
