Structure

The National Monuments Service's description

In rough, heather-covered upland bog, located on the lower SW-facing slope of a high ridge in NW of Achill Island. Ground rises steeply to NE, and falls away gradually to SE, levelling out to an area of worked bog.
This structure (L 7.5m; H 0.3-0.6m) consists of a low, trapezoidal cairn of stones, which narrows from a broad façade (Wth 5.3m) at the S end, to a markedly narrow N end (1.5m). It is engulfed in heather, sod and clumps of sedge, which make it difficult to interpret the remains and their relationship to a hut site (MA042-048002-), which stands immediately adjacent at SW.
The broad, low S façade is defined by drystone walling (H 0.6m), rising in two to three courses, and also incorporates at least one upright stone (L 1.1m; T 0.1m; H 0.5m). The W side is defined by what may be a double wall construction, with an outer wall of contiguous, upright stones/boulders (largest measures: L0.9m; T 0.1-0.15m; H 0.7m) facing an inner wall of drystone construction and/or uprights. At the narrow N end, a single upright end stone and two side stones (H c. 0.3m) appear to enclose a small chamber or box-like setting (c. 1.5m E−W; c. 0.9m N−S). Stones can be felt beneath the heather on the E side, but upstanding walling is not evident, except at the junction with the S wall. In the interior area, amidst a low jumble of heather-covered stones, there is a hint of a roughly central, narrow ‘passage’ or break extending N−S, with a prostrate slab partly overlying the S end. Appended to the SW corner of the structure is a D-shaped hut site (MA042-048002-) (c. 3m N−S; c. 3m E−W) of rough drystone construction, with a narrow entrance gap on the E side. The hut appears to post-date the trapezoidal structure, and may have been built with stones robbed from it. It is unclear to what extent the walling on the S and W sides of the structure has been modified by the builders of the hut, and to what purpose. The nature, function and date of this structure remain enigmatic.
