The double church of the Transfiguration of Christ (Sotiras Christos) and Saint John (Agios Ioannis) is located in the cemetery of the current settlement of Ancient Eleftherna, in a lush green position and close to a spring of fresh water.
The original church of the 10th century bears frescoes of the 12th century, has a dome and was built on the ruins of an older temple of the 6th century. In the dome there is a fresco of the Pantocrator of high quality, while on the floor there is a tomb.
Later in the 16th century a second temple was added next to the first. The church was probably the Diocese of Elefterna.
