Lidar Image - Great Dunmow Roman Settlement

The Settlement area is shaded in yellow and is taken from Wickenden. However our road to London I have shown in a different location based on Lidar and old mapping. It is a more logical route too.

Passing through the Rodings it makes a subtle change of direction.

Approaching Black Cat

The road to London is now just a narrow country lane. The agger is wider though giving a clue to its Roman origins. We are between Cobbler's pieces and Black Cat here.

At Moreton there is a little dog-leg for the river crossing and another a few miles further on.

The Roman bridge site and the modern bridge most likely coincide just south of Moreton over the Cripsey Brook.
