Sacred Relics (Topkapı Palace)
The various relics of Muhammad, his followers, and other items purportedly associated with Muhammad were brought to Topkapı Palace in Istanbul, where they remain to this day.
Topkapı Palace
The Mosque of the Ağas ("Ağalar Camii") is the largest mosque in the palace. It is also one of the oldest constructions, dating from the 15th century during the reign of Mehmed II. The Sultan, the ağas and pages would come here to pray. The mosque is aligned in a diagonal line in the courtyard to make the minbar face Mecca. In 1928 the books of the Enderûn Library, among other works, were moved here as the Palace Library ("Sarayı Kütüphanesi"), housing a collection of about 13,500 Turkish, Arabic, Persian and Greek books and manuscripts, collected by the Ottomans. Located next to the mosque to the northeast is the Imperial Portraits Collection.
