The tomb was excavated in the 1940s by Seán P. Ó Riordáin and Ruaidhrí De Valera when cremated bone, a polished stone hammer, flints and pottery were found.

Glencullen also has an important standing stone at Newtown Hill and also has an earthen burial mound dating from the same period as the wedge tomb at Ballyedmonduff.

At the centre of the village is Johnnie Fox's Pub, which was established in 1798, the year of the Irish Rebellion led by Theobald Wolfe Tone.

The Stars of Erin (Irish: Réaltaí na hÉireann ) are the local Gaelic Athletic Association club.

In August 1841 the village was the centre of the agitation movement against Robert Peel's government when the "cabinet council" was convened at Fitzsimon's seat.
