Summary

This coastal promontory, marked as 'Doon' on the second edition OS six-inch map, is situated at Rinardalliff Point close to Bloody Foreland in an area of cut-away turf. It is an irregular promontory projecting SW into Altawinny Bay at an altitude of 1m OD. On the landward side on the NNE a large ditch measuring c. 12m wide and 3m deep has been cut across the neck to separate the promontory from the mainland. Traces of a defensive wall can be seen along the inner lip of the ditch and along the margins of the promontory, enclosing a rectangular area measuring about 15m E-W by 10m N-S and possibly representing the 'Old Castle' marked on the 1st edition of the OS 6-inch map, while on the landward side of the ditch the remains of a ruined rubble wall of large boulders can also be seen. Numerous other structures and walls can be seen scattered across the neighbouring part of the mainland, but their relationship to the structure on the promontory is unknown (DG023-001002-5 & 7; Lacy 1983, 221)

Hillfort Type

This coastal promontory is situated at Rinardalliff Point close to Bloody Foreland in an area of cut-away turf and regenerated land. It is an irregular promontory projecting SW into Altawinny Bay at an altitude of 3m OD. A number of features were recorded here but it is not possible to say to whether they relate to the structure on the promontory (Lacy 1983, 221).

Interior Features

Besides the foundation of a large rectangular structure, possibly a Medieval Castle, on the promontory itself, a number of rectangular stone structures are also known outside the ditch on the landward side.

Enclosing Works

A large ditch measuring c. 12m wide and 3m deep separates this small promontory of c. 0.08ha from the mainland. Traces of walls around the margins of the promontory, and on the landward side of the ditch the remains of a ruined rubble wall of large boulders. Walls across other promontories on the mainland form separate enclosures, but are more likely to be old field boundaries.

Area 1:   0.08ha.
