Emhain Abhlach

Emhain Abhlach is often identified with various mythical or mystical islands in Irish mythology. One of the most well-known references is associated with the Otherwordly island where Manannán mac Lir, a sea deity in Irish mythology, resided. Manannán mac Lir is often depicted as a guardian or ruler of the Otherworld, and his residence on Emhain Abhlach is described in various tales.

There are theories that the Isle of Arran or the Isle of Man in fact is the Emhain Abhlach. Both islands have equal claim to be Emhain Abhlach, and, as is usual, no evidence exists to support the claim of one over the other. Geoffrey of Monmouth later associated this realm with Avalon.
