2. Excavation of an upland fringe later prehistoric round house by Bob Johnston and John Roberts as part of the Ardudwy early Landscapes Project, between 2001-2004.

The report from 2002 gives useful detail about the structures investigated (from Bangor University website):

'Area A (small circular embanked enclosure / probable `ring cairn?) ? evaluative excavation revealed a stone bank, the structure of which varied around the circumference. On the south and east sides, the bank consisted of a loose rubble core revetted by large pitched stone slabs that were, in one section, pitched inwards towards the core of the bank, and, in another segment, pitched outwards. A redy brown soil sealed beneath the bank was interpreted as a possible sealed land surface. On the north and west sides of the enclosure there was less pattern to the spreads of stone. Within the interior, towards the north-west side, a large shallow oval pit was uncovered. The pit was filled with a dark brown, organic rich soil with frequent small charcoal inclusions. The southern half of the pit was sealed beneath a substantial stone slab.

Area B (complex embanked enclosure / possible hut circle settlement with later reuse) ? evaluative excavation exposed a complex pattern of deposits that can only be partially understood from the limited investigations that were undertaken. On the west side, within the enclosure, a series of roughly cobbled and paved floor surfaces were found, the most regular of which lay inside an arc of walling and is taken to represent the interior of a hut circle. An irregular cobbled surface extending beyond the arc of stones is interpreted as a surfaced yard or working compound external to, but contemporary with, the hut circle. A series of poorly defined stakeholes were noted cutting this floor deposit. A pit, containing significant quantities of burnt stone as well as a few pieces of burnt clay and fragments of charcoal, was sealed by the cobbled floor surface and truncated by one of the stakeholes. The outer wall of the enclosure overlay a broad shallow feature which is interpreted as a slight hollow way formed at the edge of the cobbled yard. The earth and stone / boulder walls visible on the surface of the site prior to excavation appear to derive from later reuse, possibly medieval or post-medieval, which respects and possibly part-utilises the outline of the earlier hut circle settlement.'
