[8] It was excavated in 1849 by members of the Royal Irish Academy who found a stone-lined cist containing a pottery vessel and cremated remains, now preserved by the National Museum of Ireland in Dublin.

[9][10] In its present form, the site consists of an open circular chamber 10 feet (3.0 metres) in diameter with a narrow passage.

[6][15] The monument is not at the summit of the mountain but is located slightly to the north at a position where the view across Dublin Bay to Howth is not obscured by Two Rock.

[17] The antiquarian Weston St. John Joyce described a rude carving of a cross and a crowned figure with upraised arms on one of the rocks to the south of the summit.

[19] Although the cross is in an early Christian style, Joyce and Healy both surmised it and the figure to have been carved at some time in the nineteenth century.

[20] There is another dedication plaque in the Pine Forest, near the car park, marking the inauguration of the Dublin Mountains Partnership on 24 October 2008 by Eamon Ryan, TD, Minister for Communications, Energy and Natural Resources.
