This Dolmen is located in Ballybrack in south co. Dublin. It dates for approx 2500b.c and the capstoneĀ  has beautiful shiny quartz mixed through it. It measures 5 foot X 5 foot and probably weighs approx 12 tonnes. It would have been covered in a cairn of stones of which none survive. It is now located in the middle of a housing estate and is vulnerable to constant graffiti and being used as a fire pit!
