Westmuir lies east of Midgate, near the eastern end of the Gask Ridge. Its position is particularly useful for understanding the limits of a simple signalling-chain reconstruction. The tower was beside the road, but did not occupy the nearby summit that would have offered the most convenient long-distance views.

The remains and their investigation
The archaeological record rests chiefly on aerial evidence. Hanson and Friell's comparative catalogue records a single enclosing ditch, a south-south-east entrance and faint possible post settings on one photograph. Those observations do not establish a complete timber plan, so no precise building dimensions are reconstructed here.
Woolliscroft's field assessment found no secure direct view from Westmuir to either Raith or Bertha. A position farther north, on the summit, would have offered better connections, but that is not where the known site stands. Monitoring the road and the outlook over Strathearn may therefore help explain its location better than signalling efficiency alone.
The published roadside comparison in the Glenbank report places Westmuir on the inside of the line, about 40 metres from the road; that convention is followed in the overview diagram. The earlier catalogue's entrance orientation should not be taken as proof that every tower gateway faced the road. The diagram deliberately leaves a direct fort connection unassigned rather than drawing an unsupported arrow.
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.

Possible communication with the forts
Westmuir is a gap in the simple reconstruction, not a reason to invent a direct fort connection. Woolliscroft discussed a hypothetical intermediate site in Cultmalundie Wood, but its existence was not demonstrated. The diagram therefore shows the known towers and nearby forts while leaving Westmuir’s fort link unresolved.
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.
