It was excavated through solid limestone over a decade from 1844, finished, fitted with locks and bridges, and then never used. The water it was meant to carry preferred to flow underground through the porous rock, leaving the channel high and dry for most of the year. The Board of Works that built it issued statements blaming costs, labour shortages, and the new railways. Local people knew the real story and have remembered it ever since: the engineers failed to take account of the cavernous nature of the limestone in the district. Today the canal is popularly known as the Dry Canal, and you can walk its bed in summer.

The canal might have been quietly forgotten if not for William Wilde, the prominent Anglo-Irish surgeon, historian, and antiquarian, who built a summer house on the shores of Lough Corrib and took an interest in the local landscape.

The fully completed lock in the village of Cong still stands, an elegant piece of cut-stone engineering opening onto nothing. The excavated channel runs north through the karst, ...
