Moss Side Roman Watchtower – Evidence for a bank and timber beams

Moss Side stood north of the Roman road, east of Witch Knowe. Its surviving appearance is less informative than its excavation history: cultivation has removed the earthworks, but an early investigation recorded details of the bank and timber supports before they were lost.

The remains and their investigation

In 1900 Christison found that ploughing had already destroyed the ditch and outer mound. The inner rampart still survived. He described it as about 14 feet wide and 3 feet high, with alternating dark soil and yellow or red clay layers. The preserved bank made Moss Side unusual among the six nearby works he examined, although subsequent excavation elsewhere has shown that internal banks were not unique to this tower.

Four substantial post holes formed a square about 11 feet, or 3.35 metres, across. Three were connected by flat-bottomed cuts, interpreted as settings for horizontal beams. Those connections add something to the usual picture of four isolated corner posts, but do not provide a complete reconstruction of the upper building.

Later aerial photography recorded the ditch as a cropmark, a difference in crop growth over buried deposits. Such marks can preserve evidence of a vanished earthwork without making it visible to a visitor on the ground. The site illustrates why absence of an obvious mound does not mean that the archaeological remains have all disappeared.

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.

Moss Side on the Gask Ridge

Gask Ridge overview highlighting Moss Side, with black watchtower dots, a red Roman road and prominent blue forts. Moss Side β†’ Raith β†’ Strageath.
Moss Side 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 Moss Side; 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.
