Looking up at the underside of the Small Corbelled Dome.

This Wheelhouse circa 25 BC to 380 AD is an enigmatic structure known as Tigh na Fiarnain - House of the Fingalians - and set in an uncultivable area of almost bare rock at a height of over 900ft. It measures 5.5m NE-SW by 5m NW-SE within its dry-built wall, 1.1m thick and 1.4m high, with the entrance in the E. In the interior is a circle of seven orthostats set at a distance of about 1m from the wall, one of which is lintelled, another partially so, and possible roofing slabs lie about. On the W, an annexe, 8.5m long and 3m broad, defined by erect slabs bedded in the peat, curves round the structure. The peat in the interior has been scooped out. To the N are traces of an outer wall which appear to curve in towards the annexe wall; and to the SW are vague traces of yet another enclosure formed by erect slabs, now collapsed, and bounded by rock outcrops on the S.
