It was started by Architect Davut Ağa, continued by Architect Dalgıç Ahmed Ağa, but it was completed 66 years after the beginning of construction, by the chief architect of the period, Mustafa Ağa, during the reign of Mehmed IV.
The New Mosque (Yeni Camii) or Valide Sultan Mosque is a significant mosque in Istanbul, which was commissioned by Safiye Sultan, the wife of Sultan Murad III, in 1597. The construction of the mosque was initiated during her reign, and it was completed and opened for worship in 1663 with the efforts and donations of Hatice Turhan Sultan, the mother of Sultan Mehmed IV.
The mosque was initially designed by architect Davut Ağa, and later continued by architect Dalgıç Ahmed Ağa. However, it was not completed until 66 years after its construction began, when it was finished by the chief architect Mustafa Ağa during the reign of Sultan Mehmed IV.
The architectural design of the mosque follows the same dome plan used by Mimar Sinan for the Şehzade Mosque and by Sedefkar Mehmed Ağa for the Sultan Ahmed Mosque (Blue Mosque). However, the unique feature of the New Mosque is its dome, which rises in a pyramid-like shape, distinguishing it from other mosques.
Around the New Mosque, you will find the Valide Sultan Tomb, a sebil (a water dispenser), and the Egyptian Bazaar (Mısır Çarşısı) arcade. The mosque’s architectural style emphasizes the height of the dome and the arcades on the side facades.
The Kabataş-Bağcılar tram line runs right in front of the mosque, and beyond the tram line, you can find the famous Eminönü fishermen.
