Holy Monastery of Saint John the Theologian

Around 95 CE, Saint John the Apostle was exiled to Patmos, where he received the visions recorded in the Book of Revelation. In 1088, Saint Christodoulos built the monastery above the cave of this revelation. The site has maintained continuous monastic community since, preserving Byzantine traditions and irreplaceable manuscripts.

Around 95 CE, during the reign of Emperor Domitian, the Apostle John was exiled to the small island of Patmos in the Aegean Sea. Romans used the island for political exiles, and John's Christian prophecy was considered politically subversive.

According to tradition, John was praying in a cave on the hillside when the rocks split into three fissures, symbolic of the Holy Trinity. Through these fissures, God revealed to John visions of the end times: the fall of Babylon, the final judgment, the new Jerusalem descending from heaven. John dictated these visions to his disciple Prochorus, and they became the Book of Revelation, the Apocalypse, the final book of the New Testament.

After Domitian's death, John was released and returned to Ephesus, where tradition says he died of old age, the only apostle not martyred. But the cave on Patmos remained a pilgrimage site, remembered as the place where heaven had opened.

Nearly a thousand years later, in 1088, the monk Christodoulos traveled to Constantinople and presented Emperor Alexios I Komnenos with a proposal: grant him the island of Patmos, and he would build a monastery to honor Saint John and guard the sacred cave. The emperor agreed, issuing a chrysobull that gave Christodoulos sovereignty over the entire island. Christodoulos returned with craftsmen and began construction. Within three years, the greater part of the monastery was complete.
