Sultan Ahmed Mosque

Sultan Ahmed Mosque, widely known as the Blue Mosque, is an active imperial mosque on Istanbul’s historic peninsula opposite Hagia Sophia. Sultan Ahmed I commissioned the complex, and the court architect Sedefkâr Mehmed Ağa directed construction from 1609 to 1620. The mosque became one of the defining monuments of seventeenth-century Ottoman Istanbul, combining a large central dome, cascading semi-domes, six minarets and extensive interior tile decoration.

It formed part of a wider charitable and religious complex and also includes the tomb of Sultan Ahmed I. The building is within the UNESCO-listed Historic Areas of Istanbul and remains an important place for daily prayer, Friday worship and Ramadan observance. Its significance is therefore not limited to architecture or tourism: it continues to function as a major congregational mosque while representing the mature Ottoman imperial tradition.

Visitors should remember that the prayer hall is first a functioning sacred space. Access may be adjusted around prayer times, and respectful dress and conduct are appropriate. The name “Blue Mosque” refers to the visual impression created by its celebrated İznik tile decoration rather than to an official religious title.
