[2] According to an epigraphic inscription discovered during restoration work in 1955,[3] the mosque was built in 1196–1197 CE[4][5] by Kızılarslan ibn Ibrahim, during the rule of Qutbuddin Malik Shah, son of Kilij Arslan II, as emir of Sivas.

[7] Some scholars consider it a product of the earlier 12th century under the Danishmendid rulers (before they were annexed by the Rum Seljuks in 1178), based on the building's architectural features.

[9][11] The main structure (the prayer hall) is a low building with a rectangular floor plan and is built of cut stone.

The interior is divided into eleven aisles or naves by ten rows of pointed arches supported on thick piers, which run perpendicular to the qibla wall.

[9] Originally, there may have been a narthex here defined by another row of arches and pillars, as suggested by the existence of two small mihrabs in the northern façade of the prayer hall.

The spandrels of these arches have different decorative brickwork patterns on each façade and they are each topped by a rectangular panel with a Kufic inscription in turquoise glazed ceramic.

[15] The cylindrical shaft, which tapers slightly, features two monumental inscription bands: one near the middle and another near the top.

As of October 2023, a team of Turkish and Italian experts have prepared plans to stabilize the tower by inserting 40-metre-long steel reinforcements inside it.
