The Holy Church of Agios Ioannis the Forerunner in Axos is located in the cemetery of the settlement. It was built on the site of a proto-Byzantine church from which only the parts of the arch and the mosaic floor are preserved. The building belongs to the type of single-aisled arched temples with two slings inside. The interior of the church is decorated with well-preserved frescoes from the 14th century. They depict scenes from the life of St. John the Baptist, as well as other religious themes such as the Hand of God holding souls and depictions of the damned at the Last Judgment.
