The study subject “The mausoleums in Alexandria during the Islamic age" is regarded of great importance as it is spotlighting the Islamic architecture in Alexandria especially the religious architecture which is represented in mosques in particular. They are not ordinary mosques but they belong to “Awliaa Allah". These mausoleums were made as assort of appreciation and glorification to the owners of these mausoleum in recognition of their roles in serving Islam and Muslims through teaching many things about the religion. These Islamic characters influenced the Islamic history in general and the history of Alexandria in particular as Alexandria was regarded as a center of attraction for the Muslim scientists from all over the Arabian and Islamic countries and especially Morocco. In respect of the cultural and civilizational importance of Alexandria throughout the ages, I have chosen the subject of my study “The mausoleums in Alexandria during the Islamic age starting from the fatimide age to the ottoman age". It became clear to me through my studying to the subject that Alexandria contains only mausoleums and it doesn't have any “Mashahid belong to A Al Beit" “the descendants of our prophet". This study contains the most important and famous mosques in Alexandria according to the historical periods to which these mausoleums and mosques belong to Alexandria was the first city in Egypt ever since it was established by Alexander until it was conquered by the Arabs. It is characterized with its magnificent planning and the important geographical and strategically location. All these advantages were enough for Alexandria to be chosen as the second capital for Islamic .Egypt. Muslims have built many big mosque in Alexandria, which were taking as centers for the political and scientific meetings. Six mosques were built in the first century of Al Hijra: Soliman mosque, Al Khedr mosque, Zi Al Kaerain mosque, Amro Ibn Al Usse mosque and Al Manarah mosque.
