Jack Stones Folklore
Folklore about the Jack Stones at Greenanstown in County Meath, as collected by the National Folklore Collection (Schools' Collection) in the 1930s.
There are three very large stones in the village of Greenanstown called Jack Stones. They are supposed to have been thrown from Tara by Finn MacCool. One morning when the people of the village arose they were surprised to see an immense stone in the centre of the cross-roads and on looking around they saw two others in a field nearby.
On the village green in Greenanstown there are three large stones called the Jack Stones. Each stone weighs about six tons (about 5.4 tonnes). The three on the green are in a straight line. It is generally supposed that they were sacrificial stones, Druid's Altars, or marking a place of assembly.
