Here Mahmud II is buried.

From the Wikip[edia: Mahmud II (Ottoman Turkish: محمود ثانى Mahmud-u sānī, محمود عدلى Mahmud-u Âdlî) (Turkish: İkinci Mahmut) (20 July 1785 – 1 July 1839) was the 30th Sultan of the Ottoman Empire from 1808 until his death in 1839.

His reign is recognized for the extensive administrative, military, and fiscal reforms he instituted, which culminated into the Decree of Tanzimat ("reorganization") that was carried out by his sons Abdulmejid I and Abdülaziz. Often described as "Peter the Great of Turkey", Mahmud's reforms included the 1826 abolition of the conservative Janissary corps, which removed a major obstacle to his and his successors' reforms in the Empire. The reforms he instituted were characterized by political and social changes, which would eventually lead to the birth of the modern Turkish Republic.
