There are two excellent references to The Citadel at :
http://www.touregypt.net/featurestories/fortqaitbey.htm and
http://en.wikipedia.org/wiki/Citadel_of_Qaitbay
Built in 1477 AD by Sultan Al-Ashraf Sayf al-Din Qa'it Bay, and recently restored by The Supreme Council for Antiquities it is a wonderfully preserved example of a medieval Citadel.The harbour views from the curtain wall are magnificent and include a distant view of the Bibliotheca Alaxandrina, The New Library which we will show you later.
