The Blackrock Dolmen, by Rowan Gillespie, depicts three elegantly elongated figures holding up a large capstone to symbolise the essence of Blackrock. The figures – two male and one female – are of cast bronze, whilst the capstone is of lighter, resin bronze on fibreglass and is in the typical triangular form of a dolmen.
Located at Temple Road in Blackrock, next to the Blackrock by-pass.
