Ortakoy Mosque

The Ortaköy Mosque (Turkish: Ortaköy Camii ; actually Büyük Mecidiye Camii ) is a mosque in the Istanbul district of Beşiktaş at the port of Ortaköy . It was built on the orders of Abdülmecid I between 1853 and 1856.
On the orders of Mahmud Ağa, the son-in-law of the Grand Vizier İbrahim Pasha, a prayer house was built in 1721 on the present site of the Ortaköy Mosque. This was badly damaged in the so-called Patrona Halil Uprising in 1730 and was probably rebuilt at the end of the 1740s on the orders of Devattar Mehmed Kethüda Ağa, Mahmud Ağa’s son-in-law, with a minaret and a box for the Sultan ( mahfel-i hümayun ).
In 1853, Abdülmecid I commissioned the Armenian architect Nigoğayos Bey Balyan, son of Garabed Amira Balyan, to build a new mosque. The Ortaköy Mosque, designed in the neo-baroque style, was completed in 1856. In 1894, the building had to be renovated after an earthquake. In 1960, the foundation was reinforced. After a fire, another restoration took place in 1984.
