The Foyle and the Strabane Canal, the Erne in the 1890s and the Armagh Blackwater and Ulster Canal in the 1890s
The turf canal network on the estate of Scotts of Willsborough near [London]Derry and, a little to the east, the Broharris or Ballykelly Canal.
Here are two short pieces about canals that were never built, which in at least one case was just as well: a canal from Armagh to Moy on the Blackwater and an insane proposal for a canal from Dublin to Lough Neagh.
And here is a memorial [the link is now dead] to what was perhaps the most insane Irish waterway proposal ever. Which, given the competition, is some achievement. If folk want to move boats between the Atlantic and the Erne, or vice versa, why can’t they pay for their own cranage and transport?
