Kiziltepe or Dunaysir Grand Mosque The Kiziltepe or Dunaysir Grand Mosque was built by Artuqid Beg Yülük Arslan and completed by his brother Artuq Arslan after his death in 1204. After being neglected for many years, the mosque has been restored to its former splendor. Located in the northwest of modern-day Kiziltepe, the rectangular-shaped mosque features a long prayer hall that is preceded by an open courtyard that is roughly twice as wide. The area is flanked by halls on all three sides, but only the foundation remains on the northern side. Entry to these spaces comes from two sets of portals along one wall each, and a fifth set at the northern end. Although two minarets once stood at both ends of this section, they are no longer present. The entrance to the prayer hall is framed with nine archways of different shapes. The arches flanking the portal contain niches for mihrabs, while those on the sides have lintels in an open lunette shape. Each arch has a unique design, with decorative loops carved into the stone and multi-foliate arches. The large polychrome arch at the center holds a grand doorway, which is distinguished by two smaller similarly-colored arches on both sides and topped by a pointed archway that stretches around all three doorways. The prayer hall measures 16 x 63 meters and is divided into nine aisles with 2 arcades. The Mihrab and Minbar are located adjacent to the entrance in the center of the room, alongside a dome that spans 10 meters across. The surface of the mihrab niche is finely carved with intricate designs that are interlaced and arabesque. The mosque, which is illuminated by four windows between the squinches and six arched windows around the tall drum, has numerous casement windows between projecting buttresses on its three exterior walls. The exterior of the elongated dome is covered by aluminum panels.
