Cullenagh House, thought to have been built towards the end of the 17th century, has been entirely demolished, leaving the landscape with almost nothing to show for its presence. It is the kind of absence that archaeological work tends to make legible, though in this case, even the excavation had relatively little to say.

In May 2000, archaeologist Kenneth Wiggins carried out a test excavation along the southern side of the Ballygowan plant, where a large new extension was being planned. Four cuttings were opened by mechanical excavator, and none of them produced any archaeological material. When the development proceeded, all ground disturbance was monitored between June and July of the same year. The monitoring confirmed the earlier findings: no archaeological features were present. The single discovery of any historical note was the well, identified as likely associated with Cullenagh House. A well of this kind would have served the domestic needs of the household, providing water before piped supplies were available, and its survival underground, while the house above vanished entirely, gives it a quietly ironic quality given the site's current use as a water bottling facility.

There is little for a visitor to seek out here in any conventional sense. The site sits within the Castle Demesne area of County Limerick, now occupied by industrial use rather than anything resembling its earlier character. The well itself is not publicly accessible, and the house it once served left no visible trace above ground. What remains is essentially a record: a name, a probable century of construction, and a single feature noted during a monitoring exercise. The value of the site lies less in what was found than in what it suggests about the layers of occupation and erasure that accumulate quietly beneath working landscapes.
