External Reference (2011)

Although known as the Invergarry ROC observation post, it is situated at Laggan, on a small hill near the swing bridge over the Caledonian Canal.

The main structure is 4-sided, on a concrete base with a metal lid, bolted and padlocked in place with an adjacent, smaller square concrete structure with what appear to be ventilation shafts. There is also a capped pipe and smaller square structure at a distance of several feet from the main one. These are virtually hidden by the encroaching gorse and vegetation.

According to the Subterranea Britannica website (, the post was opened in 1960 and closed in 1991. In 2001 all surface features remained intact with some flaking of the blue/green paint. It is one of a number situated along the Great Glen, with other examples at Fort William, Spean Bridge, Fort Augustus, Drumnachrochit and Inverness.
