No structures remain visible; what survives is fragmentary, spread along the shoreline roughly 120 metres north-east of the ruins of Derryclare Lodge. The debris appears to be eroding out of what specialists call a drowned horizon, a layer of ground that was once dry land but has since been submerged or waterlogged, effectively sealing and then gradually releasing whatever was deposited there. It is the kind of site that announces itself through absence as much as presence.

The precise date and nature of the metalworking here remain unestablished, but the physical evidence suggests a site where metal was worked rather than simply stored or traded, the debris being consistent with production activity of some kind. The detail about a drowned horizon is significant: such contexts can preserve organic and inorganic material that would otherwise decay, and the current erosion means that what survives is being slowly lost to the lake. The information comes from fieldwork communicated by M. Gibbons in January 2020, placing this discovery very recently within the archaeological record. The proximity to Derryclare Lodge, itself now a ruin, adds a layering of abandonment to the site, one industrial or craft episode overlapping in the landscape with a later domestic one.
