Like Poulnabrone in the Burren, Legananny is a neolithic portal tomb, built between 4000 and 4500 years ago. The word 'dolmen' was used by early studies of antiquities and comes from the Breton (the language of Brittany in France closely related to Irish gaelic) word 'tolmen' which means 'stone table'. These monuments also gave rise to legends after which they have been named. The Giant's Grave or the Druid's altar are common local names for such features. 'Diarmud's and Grainne's bed' reflects another story from the Tain. Originally this would have had a mound covering it but most of this has been removed although there are traces on all sides of the tomb itself except for the lane on the left.
In this case the name Legananny comes from Liagán Áine or 'Pillar of Enya'. She was the mythical goddess loved by the equally mythical Finn McCool.
portal tomb is on Slieve Croob in County Down and is pictured from
the rear with the portal just visible between the two entrance stones
to the left of the rear stone and the Mourne Mountains visible
in the distance. Unlike Poulnabrone which is made of limestone,
Legananny is made of granite.
