Rather than an open pool or a simple stone-lined pit, this is a roofed, chambered structure, roughly circular in plan and shaped like a keyhole when seen from above. You descend to it: a low wall contains five steps that lead down to an entrance barely wide enough for a person, oriented to the south-east. The well itself stands about a metre above the surrounding ground level, its corbelled roof, a technique in which stones are layered inward and upward to form a self-supporting dome, finished with an external cement cap. Three iron bars prop a rough lintel of stones set on edge. The whole thing is built of sandstone with crude cement mortar, functional and unadorned.

Holy wells occupy a particular place in the Irish landscape, often associated with pre-Christian water veneration that was later absorbed into Catholic practice. The sites were frequently visited on pattern days, the feast day of a local patron saint, when pilgrims would pray, circle the well a prescribed number of times, and sometimes leave offerings of rags or small objects. The well at Inane does not broadcast its age or its dedications in the physical record as it survives. What the structure does suggest is a deliberate, careful act of enclosure, someone at some point deciding that this water source deserved to be sheltered and approached formally, by steps, through a narrowing passage, into a covered interior only 1.7 metres wide and 2.2 metres high.
