Experts from Wessex Archaeology's Coastal and Marine department will give a presentation on Lewis on how submerged areas of the Western Isles may hold clues about the first islanders to live there more than 9,000 years ago.

Archaeologists believe up to six miles of land may have been lost off the west coast of the Outer Hebrides in the past 10,000 years, potentially leaving excellent underwater archaeology sites, which can offer preservation conditions rarely seen on land.

In sheltered areas of the seabed there may be evidence of the first people to colonise the islands some 9,000 years ago.

Marine archaeology specialists Dr Jonathan Benjamin and Dr Andrew Bicket will give a public presentation on the subject in the Council Chamber, Western Isles Council headquarters in Stornoway, at 7pm on Monday 18th July.
