The Joining of the Lochs — The Seer's Prophecy of the Caledonian Canal

Caledonian Canal, Fort Augustus, Highland, Scotland

The Brahan Seer is said to have foretold that the lochs of the Great Glen would one day be joined into a single waterway from sea to sea — fulfilled when the Caledonian Canal opened in 1822, linking Loch Ness, Loch Oich and Loch Lochy end to end.

Among the Brahan Seer's prophecies concerning engineering feats not yet imaginable in his own time is one describing the lochs of the Great Glen — Loch Ness, Loch Oich, and Loch Lochy, strung roughly in a line across the width of the Scottish Highlands — becoming joined into a single continuous waterway, allowing ships to pass clean through the country from the North Sea to the Atlantic without rounding the top of Scotland at all. The prophecy was fulfilled by human hands rather than any natural flood: between 1803 and 1822, engineer Thomas Telford directed the construction of the Caledonian Canal, cutting artificial channels and building a system of locks — including the dramatic eight-lock "Neptune's Staircase" at Banavie — to connect the natural lochs of the Great Glen into one navigable route coast to coast. It remains in use today, now mostly by leisure boats and small vessels rather than the naval and merchant shipping it was originally built for. Of the Seer's prophecies, this is one of the more straightforwardly literal — a description of ships travelling from sea to sea through the middle of the Highlands, in an age when the canal that would make that possible was still two centuries away and the engineering to build it did not yet exist.
