A grotto on a hillside on the Aegean island of Patmos, venerated since antiquity as the place where the apostle John, exiled "on the island called Patmos because of the word of God," received the visions he recorded in the Book of Revelation (Revelation 1:9-11). Tradition holds that John dictated the text to his disciple Prochorus here. The site, together with the nearby Monastery of Saint John the Theologian, was inscribed as a UNESCO World Heritage Site in 1999.
Archaeology
The cave itself is a natural rock formation that has been continuously venerated and built around since at least the Byzantine period, with the surrounding Chapel of Saint Anne and monastic structures added over centuries; the earliest surviving built fabric on the site dates to after the 11th-century founding of the neighboring monastery. There is no archaeological evidence that can independently confirm John's presence in this specific cave — the identification rests entirely on a long, unbroken monastic and pilgrimage tradition rather than excavation.

Reflect
In a cave on a prison island, John heard, 'Behold, I am making all things new' — where do you most need to hear that now?
