Sahabiye Madrasah Built by its owner Ali, the Sahabiye Madrasa is a square-shaped building with a large dome in the center. It is surrounded by an open courtyard with rooms on either side, and the entrances feature arched openings, two of which are large lecture halls. Additionally, there are two small iwans on either side of the madrasa. Although some architectural features were erased or damaged during renovations in the Republican period, the grand portal of the Sahabiye Madrasa still contains impressive stone carvings both inside and outside. The madrasa was commissioned to be built by Seljuk Vizier Sahib Ata Fahreddin Ali in 1267. It consists of 41 rooms with a rectangular plan, open courtyard, and single-story. The building's appearance is related to Anatolian Seljuk architectural characteristics and is arranged around a central courtyard area of 40x30 meters. One example of Seljuk quality workmanship is the crown gate, which protrudes in mass. At the time of construction, the roads outside the madrasa were higher, so this low counterweight was designed to remain under it without becoming taller.
