Brenanstown (Glendruid), county Dublin.
O 229 241 - Sheet 50
Nearest village/town: Cabinteely, Greater Dublin
A superb granite sepulchre in a leafy glen behind secluded residences of the
rich,
this portal-tomb is unusual in being approached from above, and,
looking like stone frozen in motion upon frosty ground, it epitomises the marvellous
sculpturality
that characterises Irish portal-tombs. Note the artificial grooves on the roofstone.
Behind the tomb is a rectangular arrangement of stones which might (or might
not) be another chamber.

The stick beside the portal-stone is one metre high.
