TheJournal.ie have an article reporting on the uncovering of what they claim is part of the former City Basin, which was located to the west of the Grand Canal Harbour in Dublin 8 (the latter also filled in).
However, I am not convinced it is part of the City Basin and, in fact, the article goes on to state:
“Long since filled in, the city basin, which was situated between what is now the St James’s Hospital campus and the Guinness Storehouse, was once part of the Grand Canal’s original mainline from Inchicore to Grand Canal Harbour”
The last part of this statement is incorrect. The City Basin was separate to the canal mainline from Grand Canal Harbour and based on the location of the excavation, this feature is more likely to be connected to the canal.
