The Lighthouse of Alexandria, also known as the Pharos of Alexandria, was a monumental tower built on the island of Pharos in Alexandria, Egypt. Constructed in the 3rd century BC during the reign of Ptolemy II Philadelphus, the lighthouse was one of the tallest man-made structures in the world for many centuries. It served as a beacon for ancient sailors and marked the harbor of Alexandria, one of the most significant cities of the ancient world.
The Lighthouse of Alexandria stood at an estimated height between 120 to 137 meters, making it one of the tallest structures of its time. It was built from large blocks of light-colored stone and consisted of three stages: a lower square section with a central core, a middle octagonal section, and a circular section at the top. At its apex was a mirror that reflected sunlight during the day and a fire was lit at night to serve as a guide for mariners.
The Lighthouse of Alexandria was not merely a functional building; it also held significant cultural and religious symbolism. The lighthouse was dedicated to the Savior Gods, Poseidon and Zeus Soter. It symbolized the city's wealth and prestige, reflecting its status as a major center of commerce, knowledge, and culture. The lighthouse also became a symbol of guidance, illuminating the way for sailors navigating the Mediterranean Sea.
The Lighthouse of Alexandria left a lasting legacy as one of the Seven Wonders of the Ancient World. Its design and grandeur inspired future lighthouse construction and its representation in art and literature has cemented its place in cultural history. In many languages, the word for lighthouse is derived from the island of Pharos, demonstrating the lasting influence of this ancient marvel.
The Lighthouse of Alexandria was the prototype for all lighthouses and was the third longest surviving ancient wonder, after the Mausoleum at Halicarnassus and the extant Great Pyramid of Giza. The lighthouse was also the tallest building in existence, second only to the Great Pyramid, and its light could be seen from as far as 35 miles out to sea.
