Agia Triada Church (Endürlük Church) The Agia Triada Church, also known as the Endürlük Church, is an ancient Greek church located in the Talas district of Kayseri. Built in 1835, the church was named after the three saints Andronikos, Provos, and Tarahos. The church's inscription is written on a marble headstone in Karamanlı Turkish. Despite the threats of treasure hunters, the church has managed to survive until now, and was even protected from the outside by a high wall. However, the erosion caused by time has caused most of the paintings and motifs inside the church to lose their features. Many inscriptions on the walls have also disappeared. In addition, the bell tower was recently demolished due to a lack of maintenance.
