An inkpot and pen atop a dome What a peculiar sight. Welcome to the Defterdar Camii a 16th-century Ottoman mosque in Istanbul.

This magnificent structure wasn’t commissioned by a sultan but by Nazli Mahmut Efendi the chief finance secretary. He chose the unusual symbol atop the dome to represent his profession. Defterdar meaning ‘notebook doer’ is fitting for a man who managed the empire’s finances.

The original inkpot and pen unfortunately fell victim to a storm in 1997. But ten years later in 2007 a replica was carefully placed atop the dome. The replacement stands as a testament to the mosque’s resilience and the enduring memory of its founder.

The Defterdar Camii isn’t just a beautiful building. It holds a special place in the history of calligraphy. Mahmut Efendi was a skilled calligrapher himself. He studied under the renowned Sheikh Hamdullah. Some say his love for calligraphy inspired the unique design on the dome. His dedication to art and faith is evident.

The mosque’s complex included a school and a madrasa. Sadly the school and madrasa are no longer standing. The cheshme (fountain) however still stands. It is located near the entrance to the mosque. It adds a touch of historical charm to the site.

Mahmut Efendi’s tomb is located within the mosque’s grounds. It’s a beautiful example of Ottoman architecture. Though its original headstone is gone the tomb remains a tranquil place of remembrance. He died in 1546. His legacy continues through this mosque.

The Defterdar Camii stands as a symbol of faith and artistry. Its unique design and rich history make it truly one of Istanbul’s hidden gems. A building that reflects both faith and the dedication of one man. A reminder that even chief finance secretaries leave their mark.
