I earlier wrote: "These pictures are taken at Meriamlik, an early-Christian place of pilgrimage because the place of the martyrdom of St. Thecla is situated here. It’s about 2 kilometers from the heart of town. Emperor Zeno built a basilica here in 480 (40 x 26 meters), of which only part of the apse is still standing. It is considered to be the oldest domed basilica of which the dating is certain. St. Thecla was supposed to have been a fine lady of good birth when she met the apostle Paul and was baptized by him. Her fiancée, whom she would not marry, incited Christian-bashers against her. She miraculously escaped a number of tortures, on occasion by dressing as a man. In this disguise she followed the apostle Paul who sent her back home."
From the Wikipedia: Thecla (Apostle and protomartyr among women) was one of the followers of Saint Paul whose origin was Tarsus about 110 kilometres (68 mi) east of the church. Thecla who was originally from Konya (Iconum of the Antiquity) lived around Silifke, in a location, now called Meryemlik (meaning of Virgin Mary). There is a cave on a small hill next to Silifke which is believed to be her home in her later years. The grave in the cave probably belongs to her.
I visited several times, the most recent pictures were taken after some improvements (like better lighting) had been installed.
I add some pictures of the nearby ancient buildings, like a couple of cisterns and a probable other church.
