Promontory fort - coastal

The National Monuments Service's description

Possible promontory fort described by Casey (2003, 16) as follows; ‘A broad lowlying headland on the southwestern shore of Lambay shows signs of having been cut off from the mainland by two filled-in ditches and levelled earthen banks 6m apart running straight across the wide isthmus. The exact nature of the feature is unclear; the most likely explanation is that this was simply a levelled field boundary. However, the existence of both features parallel to one another suggest that this may be the remains of widely-spaced defensive banks cutting off the promontory. The surrounding area consists of landscaped gardens and fertile pasture, and the site is overlooked by a medieval moated site some 130m inland. The interior is featureless and the sea is easily accessible from within.’
