The only single column marks the site of what was once a huge and elaborate temple, which was constructed of marble and decorated with precious metals on the interior. Some of the tunnels around the complex remain and are open for tourists to explore and some of the artifacts from the temple have been recovered. A life-size black basalt bull from the temple and a golden plaque marking the foundation of the Serapis are on display in the Greco-Roman Museum. Qaitbay Citadel :Sultan Qaitbey built this picturesque fortress during the 14th century to defend Alexandria from the advances of the Ottoman Empire. His efforts were in vain since the Ottomans took control of Egypt in 1512, but the fortress has remained, strategically located on a thin arm of land that extends out into Alexandria’s harbor from the corniche.

The Citadel of Qaitbay is a 15th-century defensive fortress located on the Mediterranean sea coast, in Alexandria, Egypt. It was built from 1477 to 1479 AD by Sultan Al-Ashraf Sayf al-Din Qa'it Bay. The Citadel is situated on the eastern side of the northern tip of Pharos Island at the mouth of the Eastern Harbour.

The Arabic name translates to English as “the mound of potshards”, referring to the broken dishes and plates that marked the area before the tombs were discovered below. This extensive complex of impressively decorated tombs dates from the Roman Era and are considered as one of the “Seven Wonders of the Middle Ages”.

Standing on the Alexandrian Corniche, the Bibliotheca Alexandrina is a vast and striking example of modern 21st century architecture, but the building recalls something much older. The library and cultural center were inaugurated in 2002 as part of a huge project to commemorate the city of Alexandria’s legacy as an ancient center of world learning and culture.
