Flotsam and jetsam which has gathered in the bay surrounding an island church off the coast of Anglesey is being cleared up by volunteers on Saturday.
St Cwyfan's Church near Aberffraw, which is only accessible at low tide, suffers from water-borne rubbish washed in during stormy weather.
A church has stood on the site, now classed as an Area of Outstanding Natural Beauty (AONB), since 1254.
Volunteers are gathering at Llys Llewelyn, Aberffraw, from 1200 GMT.
The clean-up is being organised by Anglesey council's Countryside and AONB Service.
Community warden Rhys Thomas said: "We're looking for volunteers who'll help us clean up the bay around St Cwyfan's Church, which is often left strewn with rubbish at this time of year.
"Our aim is to sustain this Area of Outstanding Natural Beauty as well as help protect marine life."
Last year's clean-up saw 40 bags of rubbish removed from the island by 30 volunteers.
