Alexandria is the second largest Egyptian, known as "The Pearl of the Mediterranean". The city has a vibrant history, with ups and downs - founded by Alexander the Great in 331 BC, it became the capital of Graeco-Roman Egypt, then was mostly destroyed and started to develop again in the 19th century. The symbol of Alexandria was the legendary lighthouse, one of the Seven Wonders of the World. Its sights are varied; still most of them are related to historic and cultural heritage. The Qaitbay's Citadel stands as a fortress in the place of the Pharos Lighthouse, guarding the sea; the Roman Theatre, the tombs of the Cemetery of Mostafa Kamel or the Pompey's Pillar are important historical vestiges. Don't miss the various Islamic mosques and also Greek Orthodox churches. Apart of its impressive heritage, the modern Alexandria offers nice places to visit, like the 15km walkway along the harbor, named Corniche.
