41°01′45″N 28°56′23″E / 41.029071°N 28.939828°E The Odalar Mosque (Turkish: Odalar Câmîi, meaning "the mosque of the barracks" after the nearby accommodations of the married Janissaries established in this quarter in the 18th century. Also: Kemankeş Mustafa Paşa Câmîi) was an Ottoman mosque in Istanbul.[1] The building was originally a Byzantine-era Eastern Orthodox church of unknown dedication.[1] In 1475, after the Fall of Constantinople (1453), it became a Roman Catholic church, dedicated to Saint Mary of Constantinople, until finally it was converted into a mosque by the Ottomans in 1640.[1] The mosque was destroyed by fire in 1919, and since then has fallen into ruin.[1] As of 2011, only some walls remain, hidden among modern buildings.
