Amazing Places on Our Planet

The Citadel is located at the eastern entrance to the port of the eastern tip of Pharos Island. It was erected on the exact location of the famous lighthouse of Alexandria, which was one of the seven wonders of the ancient world. The lighthouse continued to operate until the time of the Arab conquest, then several disasters took place and the shape of the lighthouse was changed to a certain extent, but it continued to function. Restoration began in the period of Ahmed Ibn Tulun (around 880 AD). During the 11th century an earthquake occurred, causing damage to the octagonal part. The bottom survived, but it could not serve as a watchtower, and a small mosque was built on the summit. In the 14th century, there was a very destructive earthquake and the entire building was completely destroyed.
