The Ortakoy Mosque (officially called the Great Mecidie Mosque) is located in the new part of the city in the Ortakoy district next to the Bosphorus Bridge. Built in 1853-1854, it has two minarets.
The mosque was built in the Ottoman Baroque style. Sultan Abdulmejid I in 1853 entrusted its construction to the architect Nigoos Balyan, who erected it in the shortest possible time. Two minarets made of white stone slabs adjoin the mosque, each of them has a separate balcony (sherefe). Like all mosques built in the era of Abdulmecid I, the Ortakoy Mosque consists of two parts: the harem and the personal quarters of the Sultan "hunkar". The inside of this one-domed mosque is decorated with pink mosaics. Tall and wide windows let in sunlight and reflect the waters of the Bosphorus shimmering with all the colors of the rainbow. The prayer niche was made of marble and complemented by mosaics, and the marble of the pulpit, in turn, was covered with porphyry.
