Situated in the southern part of the Mullet Peninsula within the barony of Erris, Fallmore townland spans approximately 704 acres (2.84 km2)[2] and, as of 2011, had a population of 75 people.

[5] The church exhibits distinct architectural features: the western section showcases polygonal masonry with granite blocks firmly cemented, while the eastern gable displays regular layers with a shallow pitch.

[10] In an 1836 book, Patrick Knight, the engineer who planned and supervised the construction of Belmullet for William Carter, one of Erris's two principal landlords, describes a three-year rotation.

[10][11] In the mid 19th century, the landscape of Fallmore consisted of larger, open fields owned collectively by the entire village, interspersed with unclearly defined individual plots for families.

In contrast, today's Fallmore features mostly smaller, privately owned fields separated by clear boundaries like earthen walls or barbed wire fences.

Purchasing the neighbouring townlands of Termon and Fallmore, Palmer initiated a process of reorganising the land, from Rundale into a more efficient system, through striping, resettlement and eviction.

I thought it would be difficult to find another community exceeding in wretchedness of appearance the village of Fallmore; but I had not proceeded far when my attention was directed to a collection of hovels such as I should think is not to be found elsewhere in Ireland.

These people cultivate half an acre or so of poor and sandy soil, from which they have obtained a sufficient quantity of potatoes to last them for another month or so; but when these are exhausted, I do not know how they are to exist, for they do not appear to have any stock, and I am sure they have no money.Shaped by the Atlantic Ocean, the landscape is characterised by blown sand and a scarcity of trees due to its exposed location.

Additionally, six other species hold national importance: Common Scoter, Red-breasted Merganser, Grey Plover, Knot, Sanderling, and Dunlin.
