The Alaeddin Türbesi where one of the greatest emirs of Karaman has been buried: Alaeddin Bey, son-in-law of the Osman sultan Murat I. He died in 1388. It stands near the citadel.
The architecture and applied arts during this Karamanoğlu period tend to be conservative (late-)Seljuk.

The Karamanids (Turkish: Karamanoğulları), also known as the Beylik/Principality of Karaman, was one of the Anatolian beyliks, centered in south-central Anatolia, around the present-day Karaman province. It came into being around 1250 (following the Seljuk defeat in Kösedağ against the Ilhanlı Mongols), and grew slowly - but steadily - to become one of the oldest and most powerful Turkish beyliks during the 14th-15th century. They were the first Anatolian dynasty (in the 13th century) to adopt Turkish as their court and written cultural language instead of Persian (as the Seljuk did). The Karamanid state was terminated by the Ottomans in 1487.
