In the 1960s, Dublin Corporation looked at the Grand Canal cutting its way through the south side of the city and saw a problem to be solved with concrete. The proposal was straightforward: drain the canal, lay new sewage pipes along its bed, and pave the result into a six-lane dual carriageway. It would have been the largest infrastructure transformation in the city since the Georgian period. A petition of 100,000 signatures said no. The plan was abandoned. The Grand Canal—131 kilometres of still water, 43 locks, two centuries of engineering—survived because Dubliners decided in sufficient numbers that they preferred it as water. The canal had been built to move stout, turf, and people from Dublin to the Shannon. By 1960 the last working cargo barge had passed through, and the question was no longer how to use it but whether to keep it at all.

The Board of Inland Navigation was established by Act of Parliament in 1751. Thomas Omer received £20,000 in 1757 to start construction. By 1759 he had completed 3 km in the Bog of Alle...

Passenger revenue grew to £90,000 by that date. Anthony Trollope's 1848 novel The Kellys and the O'Kellys includes a tedious passenger-flyboat journey from P...

Grand Canal (Ireland): Breaches, Disasters, Drownings

Sat, 23 May 2026 00:00:00 GMT

Photo credit Public domain. Canals fail in two ways: they leak, or people drown in them. Both happened repeatedly on the Grand Canal. A breach in 1797 spilled water across the countryside; the same location breached again in 1855. In 1916, 300 yards of canal were displaced. The last major breach was on 15 J...
