Salters' Road.

There are many Salters' Roads in the Lothians; unsurprisingly, most of them lead to Prestonpans. Most of them were probably built by the Romans although there is no record of a Roman settlement there.
The Cistertian monks of Preston Grange, a mile or so west of "The 'Pans" established their right of access to Newbattle Abbey in the late 12th century and, to avoid conflict with the farming communities, built this particular Salters' Road and also paid for the right "in kind" by providing the landowners with building materials. There was a great economic importance of the trade in salt as it was extensively used as a food preservative before the days of wide spread refrigeration which, in turn, probably led to our current excessive consumption of it.

As a further nod in the direction of local history, a couple of miles away  on the far side of Dalkeith by the stretch of Salters' Road recognised by our postal service, there is the Salters' Inn, I cannot find any historical references to it although there would have been a need for a watering hole on this trading route.

The blip was taken where the road passes through the grounds of Newbattle Abbey.
