It was built by Külabi Ahmet Pasha during the repair of the mosque in 1622 (Dursunkaya, 1948). In the Kocahıdır District, the fountain placed as a single-sided wall fountain on the western corner of the Pasha Mosque's courtyard wall with a square plan scheme was made of cut mold. There is a single tap on a mirror stone placed in a niche with a flat-pointed arch. The keystone of the belt is fitted to protrude outward. The decorations on the façade of the fountain and on the mirror stone have saved the fountain from simplicity.
