View of the City of Dublin. The Bay, Mountains & The Royal Canal and Foster Aqueduct (1813) by JC Oben. This is the one that had me scratching my head a bit. You may know the area depicted as Constitution Hill. The famous Hendrons building would be somewhere just behind the cottages to the left. The Foster Aqueduct that brought the Royal Canal all the way to Broadstone was only removed sometime in the mid-20th Century.
