Gazanfer Ağa Madrasa is located between Unkapanı and the Women’s Bazaar, next to the Bozdoğan Aqueduct. It was built by architect Davut Ağa on the order of Gazanfer Ağa, the main custodian of Sultan Mehmed III in the 16th century. The complex, comprised a madrasa, a tomb, a fountain, and a graveyard that was added later.
