The building itself was demolished at some point between 1913 and 1944, leaving the site in Newcastle, just north-north-west of Galway city, without so much as a roofless shell. What remains above ground is effectively nothing, and yet the chapel has not entirely disappeared.

The structure was erected in 1509 to 1510 by a member of the Lynch family, one of the powerful merchant dynasties that dominated Galway's civic and commercial life through the late medieval period. It was a modest building by any measure: roughly nine metres long and four and a half metres wide, oriented east to west in the conventional manner for Christian worship. The Ordnance Survey Letters, compiled in the nineteenth century as part of a broader effort to document the Irish landscape, recorded a twin-light window, most likely set into the east gable, and an arched recess cut into one of the side walls. These details suggest a building with some architectural care put into it, even at that relatively small scale. A holy well lay approximately fifty metres to the south, a pairing of chapel and sacred water source that was common in the Irish landscape and reflects a layering of Christian and older devotional practice around particular places. The twin-light window and certain other carved fragments were salvaged before or during demolition and are now held at University College Galway, the institution now known as University of Galway, where they were recorded under a separate monument reference.

There is little on the ground today to mark where the chapel stood, and visiting the site would require some knowledge of the local topography along the Corrib's western bank. The fragments preserved at the university represent the more tangible connection to what was built here in the early sixteenth century.
