The Grand Çamlıca Mosque is a place of worship located on Çamlıca Hill in the Üsküdar district of Istanbul and holds the distinction of being the largest mosque in Türkiye. Its architecture, which blends Ottoman and Seljuk traditional styles with modern lines, has become a significant landmark in Istanbul’s skyline. The mosque was officially opened on 3 May 2019 with the participation of President Recep Tayyip Erdoğan.
Construction of the mosque, whose foundation stone was laid on 7 August 2013 on Çamlıca Hill, was completed after six years of work. The structure was built as a large külliye and serves not only as a place of worship but also integrates cultural and artistic facilities including an art gallery, a library, a conference hall, art workshops, and the Museum of Islamic Civilizations.

The Grand Çamlıca Mosque is distinguished by its main dome, which rises 72 meters high. The dome represents the 72 nations living in Istanbul, while its 34-meter diameter symbolizes the city itself. One of the mosque’s most striking features is the world’s largest crescent symbol, measuring 3 meters 12 centimeters in width, 7 meters 77 centimeters in height, and weighing 4.5 tons, adorning the top of the main dome. This crescent has been colored using nanotechnology and consists of three sections.
The mosque’s minarets are also notable. The structure has a total of six minarets, four of which are 107.1 meters high and two are 90 meters high. The heights of the minarets were designed in honor of the Battle of Manzikert. The main entrance gate is 5 meters wide and 6.5 meters high, housing one of the largest prayer doors in the world.
