Nuruosmaniye Mosque

The Nuruosmaniye Mosque (Turkish: Nuruosmaniye Camii) is an 18th-century Ottoman mosque located in the Çemberlitaş neighbourhood of Fatih district in Istanbul, Turkey, which was added to the Tentative list of World Heritage Sites in Turkey in 2016.

Designed by a Greek non-Muslim architect named Simeon Kalfa, the Nuruosmaniye mosque was the first monumental Ottoman building to exemplify the new Ottoman baroque style, which introduced baroque and neoclassical elements from Europe. The mosque's ornamentation and its curved courtyard display its baroque influences. The dome of the mosque is one of the largest in Istanbul. The mosque is part of a larger religious complex, or külliye, acting as a centre of culture, religion, and education for the neighborhood.

In Constantinople, the area of the Nurosmaniye Mosque was close to the Forum of Constantine, where the Column of Constantine (Turkish: Çemberlitaş Sütunu) still stands. Surrounding the mosque is Istanbul's Grand Bazaar (Turkish: Kapalıçarşı). After the construction of the Sultan Ahmed Mosque, the Nurosmaniye mosque was the first imperial mosque to be built in 100 years.
