An inspection of the ground at Roskeen in County Mayo found no visible trace of the old chapel that had once stood there, a building that had already been reduced to a ghost of itself for the better part of a century. What makes the site quietly interesting is not its absence but the slow, documented process of that disappearing.

The chapel appears on the 1838 Ordnance Survey six-inch map, already labelled as a site rather than a standing structure, suggesting it had fallen out of use well before the surveyors came through. By the 1920 edition of the same map, the designation had shifted again, to 'Chapel (Site of)', a cartographic acknowledgement that even the memory of the building was receding. In the first half of the twentieth century, the outline of a rectangular structure could still be made out on the ground, roughly ten metres east to west and six metres north to south, marked by low sod-covered foundations. A gap in the eastern wall was also discernible, likely the position of the original doorway, since chapel entrances in this tradition were commonly placed in the west or east gable. Then, sometime between those early decades and a recorded inspection in 1987, the last visible traces were absorbed entirely into the surrounding land.
