Turris Mains Rigg
About
Mains Rigg's watch tower sat roughly halfway between the Stanegate forts at Nether Denton and Throp, its turf-covered stone footings tracing a tower about six and a half meters square with walls a meter thick. It formed part of the relay of signal posts that let messages travel the length of the frontier road faster than any horse could ride it.
What happened here
A small stone tower with a timber top, sited so that it can see the next one along the line. Half a dozen men live in it. They watch the ground in front, and they watch the tower on either side. A signal — fire and smoke at night, something visible by day — passes a warning down the chain far faster than a rider can, though it can only carry a message that was agreed in advance. The rest of the time it is a lookout post on a road, a river crossing or a frontier line, and the work is boredom punctuated by inspections. Supplies come up from the fort behind. Towers on a frontier stand within sight of each other for hundreds of miles.
