At the foot of the Kale hill sits a building, the Taş Medrese ve Türbe. There was a grave monument for Allahudevle oğlu Merhu Mehmet Bey (and his family, you can see its' entrance).

From another source I found: "The medrese forms an integrity with the Ulu Mosque in the city square, it is by Dulkadirli Alaüddevle Bey. It is understood that he had it built at the end of the 15th century. With its single-storey, open courtyard, single-iwan madrasa plan layout, and the mosque on the south, open courtyard and student rooms complete the building. The cut stone workmanship and Mamluk style stalactite window decoration are important.

The Tomb Part: It was built in 1510 in the name of Shahruh Mehmed, the son of Alaüddevle Bey, who was murdered by the Safavids. The structure, in square form, domed from the inside and covered with a pyramidal cover from the outside, is in harmony with the madrasa. One of the sarcophagi in the tomb is the daughter of Alaüddevle and the other six sarcophagi belong to the national heroes of the War of Independence."
