Sultan Alaaddin Mosque, Antalya

Sultan Alaaddin Mosque, better known by its fluted minaret as Yivli Minare Camii, was built around 1230 under the Anatolian Seljuk sultan Alaeddin Keykubad I and is also called the Alaeddin Mosque or Antalya's Ulu Cami. Its 38-meter brick minaret, ribbed in vertical flutes, has become one of the most recognizable landmarks on Antalya's skyline and gives the surrounding complex its popular name. The mosque was never a stand-alone building but the centerpiece of a larger Seljuk religious and charitable complex that also included the Gıyaseddin Keyhüsrev Madrasa, a dervish lodge, and the mausolea of Zincirkıran and Nigar Hatun. Standing in Kaleiçi along Cumhuriyet Avenue beside Kalekapısı Square, at the edge of the old city walls, the mosque remains in active use nearly eight centuries after its construction, making it one of the oldest continuously significant Seljuk monuments on Turkey's southern coast.
