Full description

Harbour Mound, Keiss, ND36SE0002

The results from the late nineteenth century excavation of this broch suggest that it was rebuilt on several occasions. The original seaward facing entrance, with its huge triangular lintel, was blocked and replaced by another one. However in the last phase of use, the outer wall was rebuilt, the second entrance blocked and the first one re-opened. (57)

The inside of the broch had a sequence of paved floors, on top of which a layer of rubbish had built up, before the next floor was laid. Overall, the rubbish from the occupation of the broch, was 2.1m deep. It included two sherds of second century AD Roman pottery, which was probably made in France. (56)

This broch has been severely mutilated, and seaward entrance is no longer apparent although entrance on NE can still be traced. The internal scarcement and the rebuilt outer wall are evident only in N segment, and southern gallery can still be traced with a possible cell alongside, together with the remains of several internal structures, the form of which could not be ascertained. The external enclosures are now greatly mutilated. Midden material is evident in and around the walls. No trace could be found of the primary outwork to the NE, mentioned by Feacham. Now in an undulating pasture field. The foundations of building mentioned by Anderson appear to be relatively modern.
Resurveyed at 1:2500. Visited by OS (R D) 14 September 1965.

Keiss Broch originated as 1st phase broch - 1st centuries BC and AD - and was subsequently modified and re-used about 2nd century AD, and again about the 3rd century AD.
2nd century re-occupation involved blocking of original seaward-facing entrance and creation of another on NE. 3rd phase of occupation involved rebuilding of outer wall, blocking of NE entrance and re-opening of original entrance, also building of an internal scarcement. During this phase, or possibly later, interior of broch was divided by slab structures and paved at varying levels, while externally various sprawling enclosures were created.
In 1910, the broch wall survived internally to a height of about 5ft, the height of scarcement, except on N where it stood 8ft high. On the exterior the maximum height was 5ft 6ins.
Excavation by Sir Francis Tress Barry produced, among more usual broch finds, two fragments of 2nd century Samian ware and sherd of 3rd century Rhenish ware. Finds, which were unstratified, are in NMAS.
Feachem (1963) notes remains of what might have been a primary outwork a short distance to NE of broch. Anderson notes the foundations of a large rectangular building a little to S of the broch. This is probably analagous to those at the 'Road Broch' (ND36SW 1) and 'Whitegate Broch' (ND36SE 3).
