Nuruosmaniye Mosque: the Baroque Mosque at the Gate of the Grand Bazaar

Updated on October 8, 2026

A few steps from the Grand Bazaar gate that bears its name, the Nuruosmaniye Mosque ("Light of Osman") is Istanbul's first great imperial mosque in the Ottoman Baroque style. Begun in 1748 under Mahmud I and completed in 1755 under his successor Osman III, it breaks with Sinan's classical restraint: undulating façades, carved plant motifs, a great many windows (174 according to some sources) and a semicircular courtyard that is unique in the city. Less visited than the Blue Mosque or the Süleymaniye Mosque, it can be visited free of charge outside prayer times, in about half an hour.

Highlights

The dome and the Baroque façades

Seen from outside, the large dome rests on a drum pierced with windows and is surrounded by half-domes and corner turrets. The curved arches, moulded cornices and carved medallions are typical of 18th-century Baroque taste; compare them with the stricter lines of the Şehzade Mosque.

The semicircular courtyard

Unlike the rectangular courtyards of classical mosques, Nuruosmaniye's forms an arc of porticoes that extends the plan of the prayer hall. It is the most surprising feature of the monument, and the courtyard also serves as a passage to the Grand Bazaar gate.

The library and the complex's buildings

The complex also includes a tomb, a madrasa, a soup kitchen and a small library, whose Baroque architecture is easy to see from the street. The outbuildings are not always open to visitors: ask the caretaker.

The prayer hall

Inside, the light pouring through the many windows explains the name "Light of Osman". The painted and gilded decoration of the dome is richer than in Sinan's mosques.
