Arap Mosque

Arap Mosque (Turkish: Arap Camii, literally Arab Mosque) is a mosque in the Karaköy quarter of Istanbul, Turkey. The building was originally a Roman Catholic church erected in 1325 by the friars of the Dominican Order, near or above an earlier chapel dedicated to Saint Paul (Italian: San Paolo) in 1233. Although the structure was altered during the Ottoman period, it is the only example of medieval religious Gothic Architecture remaining in Istanbul.
