This fort seems to have a good defensive position, at the top of a slope one side, and at the edge of a cliff on the other (popular with climbers??). The semicircular stone banks probably originate from the iron age and there are the remains of hut circle(s) inside – but use of the location obviously goes back further, as according to ‘Keys to the Past’ a neolithic axe was found here in the 1920s.
