Early Christian Basilica
The Basilica of St. John (St. Jean Aniti) was a great church in Ephesus constructed by Emperor Justinian in the 6th century. It stands over the believed burial site of St. John, who is identified as the apostle, evangelist (author of the Fourth Gospel) and prophet (author of Revelation).A church was built over the Hellenistic city wall in the late 4th or 5th century.

Then it was converted into a three-aisled basilica with narthex and arcades. The church was abandoned after the fire in 7C AD.
Legend says that John wrote his gospel in Ephesus at the request of other disciples, then died in the church named for him on Ayasoluk Hill. Later legends developed that he was not really dead, but sleeping, and dust could even be seen moving above his grave as he breathed.

The 13th-century Golden Legend narrates John's death as follows:
According to Isidore, when John was 98 years old, that is, in the 67th year after the Lord's passion, the Lord appeared to him with his disciples and said: 'Come to me, my beloved: it is time for you to feast at my table with your brothers!' John rose and was about to go, when the Lord added: 'You will come to me on Sunday.'

When Sunday arrived, all the people gathered in the church that had been built in his name, and John preached to them at cockcrow, exhorting them to be steadfast in the faith, and zealous in carrying out the commandments of God. Then he had them dig a square grave near the altar and throw the earth outside the church.

He went down into the grave and, with arms outstretched to God, said: 'Lord Jesus Christ, you have called me to your feast: here I am, and I thank you for deigning to invite me to your table. You know that I have longed for you with all my heart!' When he had said this, he was surrounded by a light so brilliant that he was lost to human sight. Then, when the light faded, the grave was found to be full of manna. This manna is still produced there to this day, and it covers the floor of the grave, looking rather like the fine grains of sand at the bottom of a spring.
St. John's basilica was roofed with six huge domes. The capitals facing the central aisle bear the monograms of the Emperor Justinian and his wife Theodora.

The current entrance leads into the basilica through the southern transept. Originally, the entry was through the exterior courtyard atrium to the west of the nave.
Recent excavations revealed a baptistery and central pool, along with an attached chapel covered in frescoes depicting the saints.
