Patmos

An island off the coast of Turkey, where John wrote the book of Revelation.

Tradition states that John was in exile there. There are a couple marks against that idea—first of all, the text doesn’t say it. All it says is that he was there due to his testimony of Jesus, but this may be because he was called to proclaim the gospel there.

Secondly, Patmos wasn’t a place of exile. It is possible that other, smaller islands near Patmos were places of exile, but Patmos was a part of the Roman Empire. This is not to deny the tradition, but the tradition could be a misreading of the text.
