The hillock itself is known as Knockanewin, a name that the antiquarian James Grove White, writing between 1905 and 1925, identified with Tulach Mhin, an early ecclesiastical foundation associated with the saint. The remains sit in the north-western corner of a burial ground, tucked within a small rectangular enclosure measuring roughly twelve metres across each way, and the stone mounds within it may trace the outline of a rectangular structure with an interior of around eight by five metres. A low bank of earth and stone defines the larger enclosure around the whole site.

Saint Molaga, also known as Laisren or Molaga of Tulach Mhin, was an early Irish monastic figure with strong associations with counties Cork and Tipperary, and his foundations are scattered across the region. Grove White recorded that he was told locally the burial ground marked the very spot where Molaga first established a church in the area, and when he visited he noted what he described as signs of the old church's foundations still visible on the hillock. The claim is unverified archaeologically, but the alignment of local placename, oral tradition, and physical remains gives the site a quiet coherence. Early Irish churches of this period were typically modest timber or dry-stone structures, so the absence of dramatic masonry is entirely consistent with the period the tradition invokes.
