THE Nautical Archaeology Society (NAS) will hold a maritime field school on Anglesey this weekend to commemorate the centenary of the end of the First World War.

The action starts today at the Red Wharf Bay Sailing & Water Sports Club in Traeth Bychan and will last until Sunday night.

The free three-day event forms part of a Heritage Lottery Funded project instigated by the Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW).

It will be open to people of all ages with several maritime-based activities on offer throughout the weekend including exciting displays and demonstrations.

Over the course of the weekend (weather permitting), divers will be launching their boats to dive down to the wreck of the Cartagena, a steam trawler that was built during World War One that now lies around 6-miles off Traeth Bychan.

Recently, divers from the Malvern Archaeological Diving Unit have been launching their boats as part of a Bangor University project to record World War One wreck sites based around the Welsh coast.

They do so from their survey vessel the Prince Madog, situated in Menai Bridge and the results of this project will be on show at this weekend's event.
