2012:382 - BALLYGRENNAN (1), Limerick

Ballygrennan 1 was located on the proposed Coonagh–Knockalisheen Distributor Road. The excavation revealed a burnt stone spread, c. 20m in diameter, with a trough pit and pit. The burnt stone spread was subsequently cut by a field drain before being inundated with between 1-2m of construction rubble.

The trough pit was centrally located under the burnt stone spread. The pit was sub-rectangular in plan and measured 3.5m by 1.4m and was 0.36m deep. The single fill was black silty clay with frequent large angular heat-shattered stones and charcoal. A very black charcoal-rich deposit may represent burning adjacent to the south-eastern side of the trough. The south-western edge of the trough was cut by a pit. This pit was sub-circular with near vertical sides and measured 2.8m by 1.88m and 0.88m deep. The pit naturally filled with water and contained charcoal-rich fill with a high density of heat-shattered stone.
