The presence of one here, in this quiet coastal townland whose name translates roughly as "head of the water," is a reminder that the landscape of Connacht is riddled with such structures, most of them unannounced by any signage, many of them only partially investigated.

Souterrains are found across Ireland in their hundreds, most commonly associated with ringfort settlements dating from roughly the sixth to the twelfth centuries. They were often connected to a dwelling above ground, their low corbelled roofs and narrow entryways making them difficult for an intruder to enter quickly. Beyond that general picture, the specific history of this particular example at Cinn Uisce, its dimensions, its condition, who built it and when, remains formally unrecorded in any publicly available source at this time. It is a site that exists on the map, and in the ground, but not yet fully in the documentary record.
