Some of the eight cenotaph sarcophagi on the first floor of the ‘Kılıç Arslan Türbesi’; most of them are adorned with glazed tiles (with white calligraphic inscriptions on a blue background). They belong to the builder of the tomb (sultan Kılıç Arslan II, 1156 - 1192) and to seven of his successors which reigned in the late 12th and in the 13th century.

A cenotaph is an "empty tomb" or a monument erected in honour of a person or group of people whose remains are elsewhere. The word derives from the Greek: κενοτάφιον = kenotaphion (kenos, one meaning being "empty", and taphos, "tomb"). In general, a Turkish ‘türbe’ has two rooms: an upper room where the cenotaph sarcophagus/sarcophagi were placed to be visited by relatives and followers, and a room beneath where the remains of the deceased were buried.
