The Seaton Valley is a narrow valley in East Cornwall which begins on the side of Caradon Hill and goes down to the sea. Originally, it was the border between the Hundreds of East and West Wivelshire.

I wanted to write about the origins of placenames in this pretty valley. So, I've made a Google map with a little info on it about places in and around the Seaton River - I'll add to it in the future.

Also, there are images from an old map (from 1803) on this page.
