It is a fleeting, tidal link between two places that were once, in their early medieval prime, far more connected to the wider world than their remote Kerry situation might suggest. On the higher ground of Beginish, around a ridge known as Canroe, the remains of an entire small community survive: eight houses, fifteen cairns, eight animal shelters, a network of field walls, and, at the island's western end, an iron smelting site. The houses themselves are reduced to foundation stumps, their stonework stripped away long ago by later generations in need of building material, but the outline of settled, working life is still legible in the landscape.

The site was excavated in the early 1950s by M. J. O'Kelly, whose published report of 1956 remains the primary account of the complex. O'Kelly fully excavated two of the houses, along with a cairn and an animal shelter, giving a detailed picture of a self-contained community that farmed, sheltered livestock, buried its dead under stone cairns, and processed iron. The four houses now recorded in the area of Canroe, designated Houses 3, 4, 5, and 8 in O'Kelly's numbering, are distributed across the high ground and its approaches: two sit near the eastern shoreline, one close to the summit of Canroe itself, and one on the lower western slope. Together with the broader field system, they describe a settlement that made deliberate use of the island's varied terrain, placing structures at different elevations, presumably for a combination of practical and pastoral reasons.

Beginish is a small island and not served by a regular ferry, so reaching it requires some planning, but the tidal sandbar connecting it to Church Island offers an occasional, natural crossing point for those already on the water. The settlement complex on Canroe is spread across open ground, and while the individual house foundations are modest in height, the density of features, walls, shelters, and cairns clustered together gives a clear sense of how fully this apparently marginal place was once occupied.
