No walls remain, no foundation stones are visible above the grass, and the only physical candidates for its former presence are a scatter of massive boulders lying nearby, which may or may not have formed part of its structure. What survives instead is a name, preserved on the third edition of the Ordnance Survey six-inch map from 1920, where a neighbouring house appears simply as "St. Patrick's", a cartographic echo of an older tradition that placed a church of the same dedication on this ground.

Local tradition describes the site as an old church known as St Patrick's, though no documentary record pins down when it was built or when it fell into ruin. The proximity of a mass rock is worth noting. Mass rocks were flat outdoor stones, often in remote or inconspicuous locations, where Catholic priests celebrated the Mass in secret during the Penal era of the seventeenth and eighteenth centuries, when public Catholic worship was suppressed under law. That a mass rock sits close to what may have been an older church site is not unusual in the Irish landscape; the two features often cluster together, the later clandestine practice gravitating toward places already considered sacred or set apart. The church at Ballycolgan leaves almost no trace on the land itself, but the layering of a forgotten dedication, a house name on an old map, a handful of boulders, and a nearby mass rock quietly suggests a place that held some significance across several centuries.
