Muir o’ Fauld Roman Watchtower – Reading the surviving earthworks

Muir o' Fauld is one of the clearest places to see the earthworks of a Gask watchtower. It lies south of the Roman road between Kirkhill and Gask House. The timber building has disappeared, but the enclosure still helps explain how a small observation post was arranged beside the route.

Visit Muir o' Fauld

📍 Location: Muir o' Fauld, Perth and Kinross. National Grid reference NN 9821 1897.

👁 What survives: A circular mound, ditch, outer bank and causeway; one of the more legible surviving tower sites.

⭐ Best for: Reading the surviving earthworks.

🥾 Visit: Check the linked HES visitor information before setting out. Use the existing paths and follow local signs. Vegetation can obscure the earthworks; the pin marks the monument, not a parking place.

The remains and their investigation

Historic Environment Scotland describes a circular mound about 15.7 metres across, surrounded by a ditch and outer bank. A causeway leads north towards the road, approximately 15 metres away. The mound is the area occupied by the installation, not the dimensions of a timber tower filling the whole space.

The surviving form is consistent with a square timber tower protected by surrounding earthworks. Its raised position would have extended a lookout's view beyond what a visitor sees at ground level. The exact height, wall construction and number of floors should nevertheless remain matters of reconstruction. No standing Roman timber survives here to settle those details.

The site's value is also comparative. Nearby towers survive chiefly as cropmarks or excavation records; at Muir o' Fauld the relationship between mound, ditch and entrance can be followed more readily. The photographs taken in July 2020 show those earthworks and their vegetation at that date. They are not a report on current path conditions or recent forestry work.

Watching the road

The nearby road linked the larger garrisons and the smaller posts. A watchtower gave soldiers an elevated position from which to observe traffic and the surrounding ground. The close spacing of these installations makes sense for surveillance as well as communication: recognising movement on a road is a different task from seeing a distant warning signal.

Modern trees, field boundaries and road surfaces are later parts of this landscape. They can hide both the earthworks and former sightlines. A modern ground-level view should therefore be compared cautiously with the possible outlook from a timber platform.

Muir o' Fauld on the Gask Ridge

Gask Ridge overview highlighting Muir o' Fauld, with black watchtower dots, a red Roman road and prominent blue forts. Muir o' Fauld → Raith → Strageath.
Muir o' Fauld is ringed in gold. All 18 towers in this series are numbered; forts are blue. Road bends and roadside offsets are schematic, and the eastern road alignment is provisional. The separate signalling diagram shows an interpretation, not a recorded message route. Original diagram: Romans in Scotland, after the Roman Gask Project reports, Woolliscroft (1993), and the Glenbank report, Table 2. Click to enlarge.

Possible communication with the forts

In Woolliscroft’s proposed network, the ridge-top towers as far east as Midgate could communicate with Raith. Raith could then relay a signal to Strageath. The diagram shows this possible two-stage connection for Muir o' Fauld; it does not claim a demonstrated direct view to the fort.

These links depend on assumptions about tower height and visibility. Vegetation, weather and whether the installations were occupied at the same time also matter. Neither the diagram nor the surviving earthworks establishes a signalling code, a fixed watch rota or the size of a tower crew.
