Shifted sands reveal Roman settlement in Alderney
A "substantial" Roman village has been found preserved beneath sand in the Channel Islands.
Excavations on Longis Common in Alderney revealed walls, a stone courtyard, pottery and coins.
The site is thought to date back to the 2nd Century BC, which is "considerably earlier" than previous discoveries.
Experts say the sand could have buried the island's first main settlement after its occupants moved to where the modern town is now.
Archaeologist Dr Philip De Jersey said the new village is connected to Iron Age burial sites in the area which are "much richer" than other burials in the Channel Islands.
"It suggests that at least some of the population had some wealth and social status - these were not all impoverished peasants living on the very edge of the Roman Empire," he said.
Dr De Jersey said the "enormous" site may spread across 15,000 sq m (3.7 acres), making it the largest settlement found in the Channel Islands and nearby areas of France.
In 2011, a building near the new settlement - known locally as the Nunnery - was found to be of Roman origin from the 4th Century AD. It is now thought to be one of the best preserved small Roman forts in Britain.
Archaeologists say the new settlement may have been connected to the fort at some point in its history.
Dr Jason Monaghan, a local historian, said one of the unique things about the site was the way it was preserved.
"(At) most Roman towns, when they fell into ruins, the locals nicked all the stones to build their farms and cathedrals and things," he said.
"What has happened at Longis is the buildings have gone out of use, the sand has blown in and buried them under three, four feet of sand........everyone would have forgotten about them."
Alderney (Riduna) in the Roman period
- Alderney, or Riduna, was part of a group of islands the Romans called Insulae Lenuri
- Based on finds, the island is thought to have been visited by ships from the Mediterranean carrying Roman pottery and wine as early as the 2nd Century BC
- Longis, where evidence of the settlement was found, is thought to have been a "natural harbour"
- The late Roman fort built near Longis is thought to have bern used to guard a naval base in the area
- At some time after the fall of the Roman Empire the settlement at Longis is thought to have been abandoned
- By the medieval period, St Anne, the island's only town, was occupied
