The Lighthouse of Alexandria was built between 280 and 247 BC.
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.
Alexandria's lighthouse was built using solid blocks of granite and limestone. The Lighthouse took 12 years to construct, and was built between 290-270 BC/BCE. After 1500 yrs. the lighthouse was knocked down after several earthquakes, but some parts of the lighthouse still remain on the shore of the harbor and in the water.
The construction of the Lighthouse of Alexandria, also known as the Pharos of Alexandria, is estimated to have required thousands of workers. Historical accounts suggest that around 300 skilled laborers, along with many more laborers and craftsmen, were involved in the project, which took about 12 years to complete under the reign of Ptolemy II Philadelphus. The total number of men involved varied over time due to the scale of the project and the need for ongoing maintenance.

When the Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World, was destroyed by a series of earthquakes between the 4th and 14th centuries, the Egyptians took measures to restore the site. They repurposed some of its stones for other building projects, including the Citadel of Qaitbay, which was constructed in the 15th century at the same location. While there were efforts to commemorate the lighthouse, its original structure was never rebuilt, and it became a symbol of lost ancient engineering prowess.
