Four Knocks is a neolithic passage tomb built about 5000 years ago. It is located 10 miles southeast of Newgrange between Ardcath and the Naul in County Dublin. The name Fourknocks may be from the Irish 'Fuair Cnocs' meaning 'Cold Hills'.
The graveyard surrounds the ruins of an old church built in the year 1710 by Charles Hussey and his wife Mabel Barnewall, close to the ruins of an old Norman Castle, in Naul village.
