It comes after it emerged the chimneys may have to be encased in fibreglass or concrete to be preserved. Responding to a query from Green Party Councillor Claire Byrne, Dublin City Council said such measures may be necessary to ensure the landmarks’ long-term survival. The council said: “It is accepted that the chimneys, although no longer in use, now have become an iconic feature in the Dublin Skyline. “The issue is that the stability of the chimneys in the longer term may give rise to the need for the structures to be encased in a new concrete or fibreglass casing. These interventions are likely to alter the appearance and integrity of the structures as originally designed.”
