Appraisal
Built by the Grand Canal Company in 1793, Blundell aqueduct, was partly funded by the local landlord and named after him. The canal did not open, however, until 1797. It is the only structure in Offaly that carries the canal over a road. Usually a canal was dug out of the ground, but at certain stretches of the waterway, such as in Edenderry, the canal was constructed by building up banks for the canal on top of the bog. The result is a raised canal that is at a higher level than the land and roads. This aqueduct was constructed to pass over an existing route into Edenderry. The canal narrows as it passes through a limestone quay as is flows over the aqueduct. In the limestone quay walls are vertical channels that accommodate stop planks should the canal breech, as it did on this stretch of the canal in January 1989.
