An underground chamber dating back 2000 years has been uncovered during work to build a house in Ness on the Isle of Lewis, Outer Hebrides, Scotland.

The Iron Age subterranean structure was revealed during the digging of the foundations for the house. Local archaeologists describe it as a stone-lined, flat stone-roofed structure, of the type known as Atlantic roundhouses, or wheelhouses, of the later Iron Age. Archaeologist Chris Borrowman believes it to be the sixth to be recorded in the area. The Prehistoric feature is said to be well preserved. After examination and recording it is said to be filled in and covered over to be preserved. Further construction is scheduled after all archaeological fieldwork is completed.
