The Lighthouse of Alexandria, one of the most fascinating architectural wonders of the ancient world, was strategically located on the island of Pharos, off the coast of Alexandria, Egypt. This remarkable structure, built during the Ptolemaic Kingdom in the 3rd century BC, stood as a towering sentinel, guiding ships safely into the bustling port of Alexandria, which was a major center of trade, culture, and learning in the Mediterranean.
The island of Pharos, where the lighthouse was situated, was a small, rocky outcrop located about 1.5 kilometers off the coast of Alexandria. The island was connected to the mainland by a narrow causeway, known as the Heptastadion, which was built to facilitate the transportation of goods and people between the island and the city. The location of the lighthouse on Pharos Island was chosen for its unique combination of geological and strategic advantages, including its proximity to the port, its visibility from the sea, and its ability to withstand the harsh marine environment.
