The Lighthouse of Alexandria, also known as the Pharos of Alexandria, was a magnificent structure situated on the island of Pharos in Alexandria, Egypt.
Constructed during the 3rd century BCE under the reign of Ptolemy II Philadelphus, this architectural marvel was designed by the Greek architect Sostratus of Cnidus.
Standing at an estimated height of 100 to 120 meters (330 to 390 feet), the lighthouse served as a guiding beacon for sailors entering the harbor of Alexandria.
Its construction materials included limestone blocks, forming a square base, octagonal middle section, and cylindrical top.
Regarded as one of the Seven Wonders of the Ancient World, the Lighthouse of Alexandria symbolized the wealth and power of the city and continues to captivate the imagination despite its ruins being damaged by earthquakes and other natural disasters over the centuries.

4. Believed to be around 100 to 120 meters (330 to 390 feet) tall
The Lighthouse of Alexandria was an exceptionally tall structure for its time. While exact measurements are not available, historical accounts and estimates suggest that it stood approximately 100 to 120 meters (330 to 390 feet) tall.
This impressive height allowed the lighthouse’s light to be visible from a great distance, guiding ships safely to the harbor of Alexandria even during nighttime or adverse weather conditions.
5. Served as a guiding beacon for sailors entering Alexandria’s harbor
The primary purpose of the Lighthouse of Alexandria was to serve as a navigational aid for sailors and ships entering the bustling harbor of Alexandria.
It emitted a powerful light, either through a large fire or reflecting mirrors, to guide ships along the coastline and help them navigate safely to the harbor.
The lighthouse’s light would have been a vital reference point for sailors, ensuring their safe passage and facilitating trade and commerce in Alexandria.
6. Made of limestone blocks with a square base, octagonal middle section, and cylindrical top
The structure of the lighthouse was composed of various architectural elements. It consisted of three main sections: a square base, an octagonal middle section, and a cylindrical top.
The lighthouse was constructed using sturdy limestone blocks, meticulously assembled to create a robust and visually striking edifice.
The square base provided a solid foundation, while the octagonal middle section added structural stability and aesthetic appeal.
The cylindrical top housed the mechanism for emitting light and potentially held statues, including a prominent statue of the sea god Poseidon, further enhancing the lighthouse’s grandeur and symbolism.
The combination of these architectural elements resulted in a distinctive and iconic structure that represented the architectural prowess of the ancient world.
7. Damaged by earthquakes over the centuries
Throughout its existence, the Lighthouse of Alexandria endured several earthquakes that caused varying degrees of damage. The most significant damage occurred in the 14th century CE when a series of earthquakes severely affected the structure.
These earthquakes led to the collapse of parts of the lighthouse, including its upper levels. Subsequent earthquakes and natural disasters further contributed to the deterioration of the ruins over time.
8. Ruins were further damaged by additional disasters
In addition to earthquakes, other disasters took their toll on the remains of the lighthouse. Natural elements such as erosion, coastal storms, and the relentless waves of the Mediterranean Sea eroded the exposed remnants of the structure.
Human activities, including the salvaging of stones for other construction projects, also contributed to the gradual disappearance of the lighthouse’s remnants.
9. Used in the construction of the Citadel of Qaitbay in the 15th century CE
In the 15th century CE, Sultan Qaitbay of the Mamluk Sultanate recognized the historical significance of the Lighthouse of Alexandria and sought to preserve its legacy.
