Barton-on-Sea looks out to Christchurch Bay on the south coast of England  between Lymington and Christchurch. It is bounded by Chewton Bunny to the west and Becton Bunny to the east  (Bunny is a local name for a wooded ravine leading to the sea.) Barton has earned fame by giving its name to a type of fossil bearing clay found in its cliffs.
