Dolmen

Situated on a natural ridge overlooking the Liffey Valley, inside the Chapelizod gate at Phoenix Park. Known as 'Cnoc-Maraidhe' or 'Hill of the Mariners'. In the early 19th-century a mound stood on the site. Excavations exposed the central cist containing two crouched skeletons accompanied by a shell necklace, flint knife and bone toggle. Four small cists were also discovered, containing cremated bones and food vessels, two of which were bowls (Wood-Martin 1895, 281, Fig.74; Waddell 1970, 115; Waddell 1990, 81). All that survives today of this cemetery mound is the central megalithic cist comprising a flat slab lying on two boulders set into concrete. There are holes in the face of the stones. Ryan (1981, 142) and Brindley and Lanting (1989-90) classify this monument as a Linkardstown-type burial of Late Neolithic date. Compiled by: Geraldine Stout Upload date: 28 September 2011

Portal dolmen; likely constructed during the Neolithic period (c. 4000–2500 BCE). Its location on a prominent ridge overlooking the Liffey Valley suggests ritual or ceremonial significance, possibly linked to early maritime or trade routes in the region.
