The retaining wall contains the probably built-up small island on which the church is situated, but has no readily dateable features. It is likely that it is late medieval in origin, though there is evidence of extensive subsequent repair.


Retaining wall to island. Rough rubble walls, battered and angled to enclose the irregularly shaped small island. Stone steps incorporated within curved inset on the landward side, with simple iron rail.

Reasons for Listing

The wall serves to enclose the entire small island and is therefore a highly significant landscape feature and a very important part of the setting of the church.
