At Kilfrush in County Limerick, that is precisely the situation. The burial ground associated with the medieval parish of Kilfrush once contained the remains of a church, yet by the early twentieth century a Mr. Gubbins, on whose demesne the site lay, had flattened the ground. What survives today is essentially a negative space, a roughly square enclosure of approximately thirty metres across, with the church site once occupying its centre.

The antiquarian Thomas Johnson Westropp, writing in 1904 to 1905, noted tersely that the graveyard had been levelled by Gubbins, recording also the presence nearby of a holy well known as Tobercolman. Holy wells in Ireland are typically ancient water sources associated with a local saint and often linked to patterns of seasonal devotion. The well's name suggests a dedication to Saint Colman, a common figure in early Irish ecclesiastical geography. By 1840, when the Ordnance Survey Letters were compiled, the situation was already advanced in its decline. Surveyors observed that the graveyard contained some remains of an old church but that it was not much in use. The site sits some sixty metres north of Kilfrush House, placing it squarely within a private demesne landscape, the kind of arrangement that often made ecclesiastical sites vulnerable to the landscaping ambitions of nineteenth-century landowners.

Access to the site is complicated by its position within what was the Gubbins demesne. The square enclosure is the main thing to look for, since the church fabric itself is gone and the ground has been levelled. The associated holy well, Tobercolman, is recorded separately and would reward cross-referencing if visiting the area. Anyone with a particular interest in the ecclesiastical landscape of County Limerick will find Kilfrush instructive precisely because of what is absent, a parish site reduced by private intervention to an outline in the ground.
