This is St.Ishmael church, in the small parish of the same name in Carmarthenshire, named after a 6th-century Breton prince and Welsh saint.
The church sits in an elevated position overlooking the estuary and at high tide the water laps the shore less than 30 metres away.
There used to be a sandbank on the estuary which was dreaded by sailors and some of the graves are of those unfortunate to have drowned there.
In the last photo, you can just make out a chain and anchor wrapped around the headstone, signifying a grave of a sailor.
