General Information

  • Location: Sultanahmet Square, Istanbul.

  • Construction Date: Built between 1609–1617.

  • Founder: Ottoman Sultan Ahmed I.

  • Architect: Sedefkâr Mehmed Agha (a student of Mimar Sinan).

  • Significance: One of the most important mosques of the Ottoman Empire and the Islamic world. Known internationally as the “Blue Mosque.”


Architectural Features

  • Design: Represents the peak of classical Ottoman mosque architecture; its central dome, semi-domes, and spacious courtyard create a balance with Hagia Sophia across the square.

  • Dome: The main dome is 23.5 meters in diameter and 43 meters high.

  • Minarets: The mosque has 6 minarets. This caused controversy at the time since the Masjid al-Haram in Mecca also had six; the issue was resolved by adding a seventh minaret to Mecca’s mosque.

  • Interior: Decorated with about 21,000 İznik tiles. Their colors and the reflection of light give the mosque its characteristic bluish tone, hence the name Blue Mosque.

  • Courtyard: One of the largest courtyards among Ottoman mosques, surrounded by arcades.


Art and Decoration

  • The interior features Islamic calligraphy panels, Quranic inscriptions, and beautifully designed stained-glass windows.

  • İznik tiles display motifs of tulips, carnations, roses, and geometric patterns.
