Abdullah Agha mosque

Abdullahağa Mosque, a mosque located in Beylerbeyi, Istanbul. It was commissioned in 1581 by Abdullah Ağa, the chief gardener of Sultan Murad III. At the same time a Sıbyan school was also built nearby.

Since the building fell into ruin over time and the foundation income had ceased, it was rebuilt by Mahmut II in 1832. The mosque has a square plan, a single dome, and a single minaret. Its garden was later paved with stone.

The mosque is situated in a low-lying area opposite Beylerbeyi Palace. Because of this location it suffered partial damage in two flood events. In 1962 a major renovation was carried out inside the mosque.
