What makes this particular structure quietly compelling is its scale and its stubbornness: a building barely four metres wide internally, constructed from large coursed limestone blocks with carefully dressed quoins at its corners, and yet its east gable still stands close to six and a half metres high. The narrow pointed window set into that gable, with its limestone jambs and pointed rear arch, draws the eye upward in a space that was never very large to begin with. The west end has largely gone, and the arches of the south windows have fallen away, but the bones of the building remain legible.

The monastery at Mungret is associated with Neasán of Mungret, whose feast day falls on the 25th of July. The site is recorded in Pádraig Ó Riain's work on Irish saints, and the cluster of churches here, of which this is one, points to a community with deep early medieval roots. The church at Dromdarrig sits roughly 90 metres south of another building on the same complex and immediately east of a structure known locally as the abbey. When the antiquarian Thomas Johnson Westropp described it in 1904 and 1905, he recorded it as measuring 14 feet by 12 feet internally, with the west end nearly levelled and only the east window-slit and two broken south windows remaining. The more detailed Urban Survey carried out by Bradley and colleagues in 1989 offers greater precision, noting the plinth on which the building sits, the wall thickness of 0.85 metres, and the possibility that the west doorway may be a later insertion. The survey stops short of assigning the building a firm date, but notes that it may be of pre-Norman origin, placing its construction potentially before the twelfth century.

The church is a registered national monument, numbered 85, which means it carries legal protection and should be approached with appropriate care. It lies within a graveyard that remains in use or at least in occasional use, so the usual courtesies apply. The east gable is the thing to spend time with, not only for its height relative to the rest of the ruin, but for the way the narrow splayed window, designed to funnel light inward while keeping the wall strong, gives some sense of the interior atmosphere the building once had. Visitors who want context will benefit from looking at the wider Mungret complex as a whole, since this church makes more sense as part of a group than as a thing standing alone.
