Moyhenna is a small townland in Mayo, a county whose boggy interior and Atlantic-facing terrain have preserved a remarkable quantity of earthwork monuments simply because large-scale modern agriculture never fully erased them.

It sits in the inventory of known monuments, noted and numbered, but its details remain to be fully documented and made public.
