Storehouse, Caledonian Canal, Corpach

Built around 1806–8, this is a rectangular rubble building with a whitewashed exterior. The south elevation features a central segmental-headed entrance with double-leaf plank doors. The building has a deep rubble eaves course and a piended slated roof. The floor interior contains stone setts. Dating from the early 19th century, the building is remarkable for its survival largely unaltered, retaining its single opening and lacking later extensions—a characteristic typical of small industrial buildings of the period.

The stables was constructed to house horses and store equipment for the masons who built this section of the Caledonian Canal. It sits at the western entrance to the canal, surrounded by other canal-related structures including offices, lock-keepers' houses, and a lighthouse. This setting is important in maintaining the building's original canal context. The Caledonian Canal Commissioners' report for 1808 mentions that a stable was built at Corpach, confirming the dating. Horses stabled here were used to haul stones up to Banavie for the construction of the locks.

During the canal's construction, horses were the primary means of transport for wagons carrying building materials and equipment. A number of single-storey workshops, stables, and stores were built at strategic points along the canal—not only at locks but also at basins and other sites of significant construction work. Several of these buildings survive, contributing to understanding the construction process and adding to the character of the Caledonian Canal.

The Caledonian Canal, which is a Scheduled Monument of national importance to Scotland, connects Inverness in the north to Corpach near Fort William in the west, linking four lochs—Loch Dochfur, Loch Ness, Loch Oich, and Loch Lochy—over a total length of 60 miles, of which only 22 miles are man-made. Designed by Thomas Telford and built to accommodate sea-going ships including Royal Navy frigates, it was on a much larger scale than other British canals, with locks that were the largest ever constructed at that time. The remote location and variable ground conditions made it a major feat of engineering. Telford served as principal engineer with William Jessop as consulting engineer. Work began in 1804, and rising costs and the project's scale resulted in slow progress; the first complete journey was made on 23–24 October 1822. Although intended for commercial use, the canal was never a commercial success and required closure for repairs and improvements in the 1840s. It became popular with passenger steamers, and tourism increased following Queen Victoria's visit on 16 September 1873.

The Caledonian Canal is one of five canals surviving in Scotland and is unique among them as the only one entirely funded by public money. It was part of a wider infrastructure initiative across the Highlands to facilitate trade, promote industrial growth, and address emigration resulting from the Highland Clearances by providing employment.
