Carraig á Mhaistin stone
Carraig á Mhaistin stone, also known as Rostellan dolmen, Rostellan Cromlech, or Rostellan Portal Tomb, is a megalithic tomb in Cork harbour at Saleen Creek. It is formed from three upright stones with a flat capstone, faces east, and sits just above the high-tide line, often covered in seaweed. The tomb is from the Early Neolithic period and is located in an intertidal area, so at high tide it is almost submerged.
It was once thought to be an 18th‑century folly built by Murrough O'Brien, 1st Marquess of Thomond, like the nearby Siddons Tower. The monument was first reported by antiquarian John Windele after his visit around 1860. A Dr. Wise later had the capstone raised after it had fallen. The accompanying cairn is in a similar position near the water and can be submerged at high tide. Public access is allowed, but only at low tide.
