Before refrigeration, salt was what made food last, and whoever controlled its movement controlled a great deal else. Across the uplands we visited, salt once travelled from coastal pans to inland valleys along a network of paths known locally simply as the salt road. The trade is long gone. A few families still keep its memory.
A trade made of people
The salt road was never one road. It was a set of routes, seasonal and flexible, walked by carriers and mule drivers who knew where to rest, which villages would trade fairly and which passes closed first in autumn. Knowledge was passed down within families, often through songs and sayings that doubled as directions.
One retired farmer we met could still recite a verse listing the springs along a three-day stretch, in order. "My grandfather sang it to the mules," she said. "It was a map you could carry in your head."
What remains on the ground
- Stone resting places — low walls at the right height to set down a load without unloading an animal.
- Chapels and shrines at dangerous points, where travellers stopped to pray before a difficult crossing.
- Place names — fields, wells and bridges still named after the salt trade, though few younger residents know why.
Keeping the memory
A small local society now records the stories of the last people who walked the routes or heard about them first-hand. They map the paths using older residents' memories, photograph the resting stones and record the songs. It is slow work, and urgent: each year there are fewer people who remember.
"We're not trying to bring the trade back," one volunteer told us. "We just don't want the knowledge to vanish without anyone noticing."
Why it matters
Histories of trade usually focus on goods and money. The salt road reminds us that trade was also a body of knowledge carried by ordinary people — knowledge that disappears quietly unless someone thinks to write it down. Time hasn't moved on from these paths so much as forgotten to look at them.
