Osman Aga Mosque

Osmanaga Mosque, also known as Osman Aga Mosque, was built in 1612 by Osman Aga and Babussaade Aga by order of Sultan Ahmed after the destruction of the Kadi Mehmet Efendi Mosque. Originally named the 1st Mosque, it was renamed the 2nd Mosque after its destruction and subsequent renovation in 1811 by Sultan Mahmud. However, in 1878, the mosque burned down in a fire in Kadıköy, and the current mosque was built in the same year. In 1880, the mosque's imam, Mehmet Asim Efendi, planted a plane tree in the mosque's garden, which became a symbol of its revival.
