What is recorded here

Three townlands still meet at the summit of Tallaght Hill, where an eighteen-metre circular mound has marked that junction since prehistoric times. People may have walked past it for generations, reading its stones as a boundary rather than a curiosity, but later they took those stones for walls, cut a drainage channel through its body, drove a forest road into its northern base and built a shooting hide on top. The southwestern edge has vanished beneath plantation trees, yet the northeast approach still reveals enough of its profile to show that the junction remains the point the mound was made to hold.

Indicated on Duncan's map (1821). Situated at the W end of an elongated rock outcrop on Tinians Hill in the centre of Lambay Island. This is a relatively small, low circular cairn (Diam.3.50m, H 0.60m) which lies on the W end of an oblong, flat-topped cairn (L. 20.30m, Wth 16.20m, H 3m; Cooney , 2009, 17).

A Neolithic cairn, likely dating to the 4th–3rd millennium BCE. Its location on a prominent hilltop suggests ritual or funerary significance, typical of early prehistoric burial practices in coastal Irish landscapes.
