Templedoomore translates roughly from the Irish as "the big black church" or "the great dark church", suggesting that somewhere beneath or beside the burial ground there once stood a significant ecclesiastical structure, now vanished or reduced to unrecognisable traces underfoot.

Graveyards bearing the "temple" prefix are scattered across the west of Ireland and typically mark the sites of early medieval churches, often associated with local saints or monastic communities that predate the Norman period entirely. The church itself may have been built in timber, or in dry-stone masonry that was later robbed for field walls, leaving only the ground it sanctified still in use. In many such sites, the dead continued to be brought for burial long after the building disappeared, the sacred character of the place persisting through generations of local memory rather than any standing structure. Tallavbaun sits in a part of Mayo where this pattern of long-continuity burial grounds is well established, and the name Templedoomore points to a foundation of some local consequence, substantial enough that its scale was worth recording in the placename.

Beyond the name and its implications, the documentary record for this particular site remains thin, and the physical remains have not been fully catalogued in any publicly accessible form. What is known is largely what the landscape and the name preserve between them.
