Archaeologists have uncovered a 2,000-year-old prehistoric settlement as part of development work on the site of the new HMP Highland in Inverness.

The excavation has led to the discovery of a roundhouse settlement relating to Iron Age and Bronze Age occupation of the site, which also contained earlier prehistoric remains dating back to at least 3,000 BC.

A wide variety of prehistoric remains were found at the HMP Highland site, including occupation areas related to domestic and industrial activities and structural evidence from the roundhouses and other timber structures.

The settlement consisted of 16 roundhouses that survived as circular alignments of postholes, where timber posts had once supported substantial hut buildings. Some of the house sites had been enclosed by palisade fencing to protect the interior.
