The mosques in Istanbul are symbols of the opulence of the Ottoman era and one of the grandest is the Suleymaniye Mosque dating from the 16th century. Curiously, the Suleymaniye Mosque takes after the appearance of the Hagia Sophia, which isn’t caused by a lack in originality, but instead, an effort to preserve and continue the rich past of Istanbul. Much debate has taken place about which design looked better, the original design of the mosque or Fossati’s baroque-inspired restoration after the 1660 fire.
