The figure of Saint John the Evangelist is also associated with Ephesus, who, according to tradition, spent the last three years of his life there and wrote his Gospel there.

Saint John supposedly brought Jesus' mother, Mary, from Jerusalem to Ephesus after Christ's crucifixion. In Ephesus, Coressus lived with her on the hill. Currently, there is a small chapel built on the foundations of the house where, according to legend, Mary lived. It is called the House of Maia the Virgin.
