Reply To: Tunnels visible on O’Connell St.

Do not underestimate how far cellars used to extend under the street.

Next time you walk around Merrion Square just look at the coal holes at the path edge.

Both Kildare Street and Leeson Street, and as we all now know Harcourt Street, have cellars or wine vaults which run well out into the street.

Presumably, O’Connell Street, when widened, did not lose the cellars from earlier building.

O’Connell Street also had underground toilets until fairly recently.
