Lighthouse of Alexandria
With a height variously expected at between 115 and 150 meters (383 - 450 ft) it was among 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 was the third big and tallest building after the two Great Pyramids (of Khufu and Khafra) for its whole life. Some scientists calculate approximately a much taller height exceeding 180 metres that would make the tower the tallest building up to the 14th century.
