These structures were constructed by hand, often roofed with large capstones, and used variously for storage, refuge, or as annexes to nearby settlement sites such as ringforts. That one exists at Cappadavock is, for now, almost all that can be said with confidence.

The archaeological record for this site is minimal in the public domain. The townland name itself, Cappadavock, derives from the Irish and points to a landscape that has been named, farmed, and noticed for centuries, but the souterrain's specific dimensions, its condition, whether it remains intact or has been partially collapsed, and any associated surface features are details not currently in circulation. Souterrains across Ireland range from simple single chambers to elaborate multi-chambered systems with low crawl-ways and tight right-angled turns, thought by some archaeologists to serve a defensive function, making pursuit difficult. Without further detail for this particular example, it sits in the record as a presence rather than a portrait.

What is clear is that Cappadavock is one of a very large number of Irish townlands where early medieval underground structures were recorded, and where the full story remains to be told. The souterrain is noted, it is there, and at some point the ground above it was considered worth the considerable labour such construction demanded.
