The Roman Road from Sandysike to Netherby and beyond, Margary 868

Netherby has turned out not to be a Roman cul-de-sac but part of probably two "new" routes into Scotland. For details of the road from Carlisle to Sandysike, where the road to Birrens branches off, see road Margary 7f.


Often previously shown dotted and only as far as Netherby, Lidar has produced convincing evidence both south and north of Netherby. I was asked if the Lidar software could pin down the location of Netherby fort - in short it couldn't or least I couldn't. Netherby House seems to have removed all traces. Luckily the roads have survived.

Our road starts at the Sandysike junction and heads towards Longtown before a turn to the north-east for Netherby. You could argue that the Birrens road is the branch and Netherby the original route.

Lidar Image - Sandysike Junction

The agger for the road to Netherby is reasonably clear although off the top of this image (north) there is no trace into Longtown so a question of joining the dots.

Lidar Image - approach to Netherby

Very obvious, very straight and very Roman.

Lidar Images - fort site at Netherby

DTM and DSM Lidar imagery cannot reveal the fort! There are probably two suitably sized platforms - the house and the walled garden.

Roy's Map of Netherby (Roy's Military Survey 1752-55)

He too does not show the location of the fort but does record a "Roman Bath". Also visible at the top is Liddel Strength Motte and Bailey. The map has been rotated to place north at the top.

This was the section that suddenly revealed that Netherby was not a dead end but lay on a road into Scotland.

3D Lidar View - Redbank

The Roman road is clear over Redbank passing the (later) Motte and Bailey and heading for a crossing of Liddel Water west of the old railway viaduct.

Lidar Image - North of Liddel Water

One road is clearly heading up Eskdale to Broomholm Roman Fort (south of Langholm) and the second up Liddesdale for............... ? The modern B6357 probably covers much of this road at least initially. Destination then Bonchester Bridge is an interesting name but that is just my guess!
