The Lighthouse of Alexandria took 12 years to build. Archaeologists will never Know exactly how long it took, as many different sources all say different things.
The ancient Lighthouse of Alexandria, also known as the Pharos of Alexandria, is believed to have had approximately 300 steps leading to its summit. This impressive structure, one of the Seven Wonders of the Ancient World, stood on the small island of Pharos and served as a guiding beacon for sailors. The lighthouse was renowned for its height and architectural sophistication, although it was eventually destroyed by a series of earthquakes.

The first lighthouse of Egypt was the Pharos, of Alexandria. The height of the lighthouse of Alexandria was estimated to have been between 115 and 135 m, or 380 and 440 ft, as 10th century travellers reported it as being 300 cubits high. To give a comparison, a 40 storey modern building is about 134m in height.

The Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World, parallels modern lighthouses in its primary purpose of guiding and safeguarding maritime navigation. Both serve as iconic symbols of resilience and human ingenuity, with their towering structures designed to be both functional and visually striking. Additionally, the lighthouse represents a beacon of knowledge and enlightenment, akin to institutions like libraries and universities that aim to illuminate minds. Lastly, just as the Lighthouse of Alexandria stood as a cultural landmark, many contemporary lighthouses also embody local heritage and history.
The Lighthouse of Alexandria, also known as the Pharos of Alexandria, is estimated to have weighed between 2,000 and 4,000 tons. Its massive structure, built primarily of large blocks of light-colored stone, stood approximately 100 meters (330 feet) tall. This monumental weight contributed to its stability and durability, allowing it to withstand the elements for many centuries before its eventual destruction.
