Scaffolding made from timber was erected around the structure, enabling workers to move freely and safely as they assembled the walls. This tier incorporated interlocking stones, a technique that enhanced the overall stability of the tower. The octagonal design also necessitated precise stone cutting, ensuring that each piece fit perfectly into the complex geometry of the structure.

As the lighthouse reached its uppermost tier, the methods became even more intricate. The cylindrical section was constructed using lighter, more manageable stones, reducing the load on the lower tiers. Workers employed a system of pulleys and counterweights to hoist materials, demonstrating an advanced understanding of mechanical principles. The final stages of construction involved installing the beacon mechanism and the crowning statue, both of which required exceptional craftsmanship and precision.

Materials Used

The materials employed in the construction of the Lighthouse of Alexandria were carefully selected to ensure both durability and aesthetic appeal. The primary material was a high-quality limestone, quarried from the region around Tura, near Cairo. This limestone was known for its fine grain and strength, making it an ideal choice for such a monumental structure. The stones were skillfully cut and shaped, allowing for precise fitting and a smooth exterior finish that contributed to the lighthouse’s imposing presence.

Granite was another significant material used, particularly for the more exposed parts of the structure. This durable stone, sourced from Aswan, was employed for its resistance to weathering and its ability to withstand the harsh coastal environment. The use of granite not only provided additional structural integrity but also added a contrasting color and texture to the lighthouse, enhancing its visual impact. The combination of limestone and granite exemplified the builders’ understanding of material properties and their ability to utilize local resources effectively.

The interior of the lighthouse featured an extensive use of marble, a material prized for its beauty and elegance.
