There is nothing to see now, no stonework, no foundation lines, no votive remnant of any kind, yet the 1838 edition of the Ordnance Survey six-inch map marks the spot with the careful designation "R.C. Chapel & Altar", suggesting it was still well enough remembered at that point to be considered worth recording by name.

The landowner's account identifies it as a penal chapel, which places it within a particular and widespread chapter of Irish Catholic practice. Penal chapels were informal or semi-clandestine places of worship that emerged during the Penal Laws era, the body of legislation from the late seventeenth and early eighteenth centuries that severely restricted Catholic religious life in Ireland. With priests prohibited from officiating openly and Catholic church-building effectively suppressed, congregations gathered instead at improvised outdoor locations, sometimes at a flat rock or rough stone structure used as an altar, sometimes in rudimentary shelters. These sites were often chosen for their slight elevation or natural seclusion, practical considerations when worship carried legal risk. The hummock at Skecoor fits that pattern, a small rise in otherwise open ground, visible enough for a congregation to find but unremarkable to a passing stranger.

By the time the Ordnance Survey cartographers came through in the 1830s, the Penal Laws had been substantially dismantled, and Catholic Emancipation had been achieved in 1829. That the site was still named and mapped suggests it retained local meaning even as the immediate necessity that created it had passed. Whatever structure stood here, whether a simple lean-to or a more defined chapel building, has left no mark on the surface of the ground.
