7 Wonders of the Ancient World

7 of 8
Slide 6

The Lighthouse of Alexandria


The Lighthouse of Alexandria was built on the island of Pharos in the city's harbor. The tower measured between 380 and 490 ft high, making it the third-tallest building in the world (the two pyramids at Giza were the tallest). Originally, it was simply a large beacon, but was converted to a lighthouse in the 1st century B.C. It stood longer than all of the wonders save the pyramids, but was eventually destroyed by an earthquake in the 13th century.
