It was built on the foundations of the earlier Havuzlu kiosk by the royal architect Mimar Beşir Ağa in 1719 on orders of Sultan Ahmed III for the use of the officials of the royal household. The colonnade of this earlier kiosk now probably stands in front of the present Treasury. The library is a beautiful example of Ottoman architecture of the 18th century. The exterior of the building is faced with marble. The library has the form of a Greek cross with a domed central hall and three rectangular bays. The fourth arm of the cross consists of the porch that can be approached by a flight of stairs on either side. Beneath the central arch of the portico is an elaborate drinking fountain with niches on each side. The building is set on a low basement to protect the precious books of the library against moisture. The walls above the windows are decorated with 16th - 17th century İznik tiles of variegated design. The central dome and the vaults of the rectangular bays have been painted. The decoration inside the dome and vaults are typical of the so-called Tulip Era, which lasted from 1703-1730. The books were stored in cupboards in the walls. The niche opposite the entrance was the private reading corner of the sultan.
The library contained books on theology, Islamic law and similar works of scholarship in Ottoman Turkish, Arabic and Persian. In those days the library contained more than 3,500 manuscripts. Some are fine examples of inlay work with nacre and ivory. Today these books are kept in the Mosque of the Ağas (Ağalar Camii), which is located next to the library in the western direction. One of the important items is the so-called Topkapi manuscript, a copy of the Holy Koran from the time of the third Caliph Uthman Ibn Affan. |
