That modest dip, noted on the eastern side of a local ringfort, is what archaeology has to offer. The rest lives in local memory.

A souterrain is a deliberately constructed underground passage or chamber, typically dry-laid in stone, built during the early medieval period and associated with nearby settlement enclosures such as ringforts. They served variously as storage spaces, refuges, or escape routes. The one at Gowlane may no longer exist in any recoverable form. When P. J. Hartnett visited in 1939, he recorded a shallow pit on the eastern side of the adjacent ringfort and suggested it might mark the location of a souterrain that had collapsed inward. Even that depression has since disappeared; there is now no visible surface trace at all. What persists alongside the archaeological note is a local tradition of an underground passage, the kind of folk memory that sometimes points toward something real and sometimes simply accumulates around a landscape that feels, to the people living in it, as though it ought to have secrets.
