Kazlıçeşme was assigned for slaughterhouse, tannery and chandlery by a decret of Ottoman sultan Mehmed the Conqueror (reigned 1444–46 and 1451–81) soon after the conquest of Constantinople in 1453.
[3][5] After all the leather industry left Kazlıçeşme, the old factory buildings were demolished, and the area became a big public space, which is used today for political and social activity rallies.
The railway station of Kazlıçeşme, which served the Sirkeci-Halkalı commuter rail line was taken out of service on March 1, 2013 in the frame of improvement works for the Marmaray project.
