A mosque complex (külliye) was constructed on the site in 1458 by the Ottoman Turks only five years after the conquest of Constantinople in 1453.
By the end of the 18th century the mosque was in a ruinous state, perhaps as a result of earthquake damage, and in 1798 sultan Selim III ordered the whole structure other than the minarets to be pulled down and rebuilt.
This work was completed in 1800.
The eastern minaret was rebuilt in the original style by Mahmud II in 1822.

Eyüp Sultan is believed to have died during the first Arab siege of Constantinople in the 670s.
His tomb is greatly venerated by Muslims.
The mausoleum is on the north side of a courtyard opposite the main entrance to the prayer hall of the mosque.

The mosque was the traditional site for the coronation ceremony of the Ottoman Sultans, where the new sultan was girded with the sword of Osman.
The Eyüp Sultan Mosque is Turkey's oldest and most sacred mosque.
Its style was changed a couple of times when the Ottomans built it based on their style and architecture during their time, however, when Sultan Selim III took over in the 1800s, he rebuilt the mosque in the Baroque style after an earthquake as previously mentioned.
Its new architecture consisted of crystal chandeliers, iznik tiles, and a mixture of different architecture that resembles different time periods.
This mosque is next in line of being one of the most important sites for Muslims with Mecca in Saudi Arabia being the first making a significant symbol for Islam.
The history behind its name goes back as far as the time of Muhammad where his closest and trustworthy friend was named Eyüp.
In addition, this mosque is surrounded by the tombs of significant people that are buried there, which attracts many more Muslims.
An important fact that many people confuse is Abu Ayyub al-Ansari's name, which is Eyüp Ensari in Turkish.
It was also believed that Abu Ayyub al-Ansari was buried somewhere around the mosque where people had continuously searched for him.
In 1458, the tomb was found and the mosque was built next to the tomb.
The initiative to build this mosque was during the times of Mehmet the Conqueror where his teacher's dream, Akşemseddin, was to build a mosque in the remembrance and burial place of Eyüp Ensari.
Another reason why this mosque is also extremely important for Muslims is due to the reason that the mosque also holds a couple of the personal belongings of Muhammad that have been preserved.
One important individual's tomb who is also here belongs to Sokollu Mehmet Paşa.
This person was an Ottoman vizier, or chief minister, who served in 1565 under Süleyman the Magnificent and Selim II.
Sokollu Mehmet Paşa was also drafted into a child devşirme (collection or gathering in Turkish) and was ranked as one as the highest in the group.
