Overview

History & significance

Castle Linglas is a broch located on Keiss Links in Caithness, Scotland. This Iron Age stone tower forms part of the distinctive broch tradition that flourished in northern Scotland during the first centuries BC and AD. Built upon bedrock of Middle Old Red Sandstone conglomerate, sandstone, siltstone and mudstone of Devonian age, the monument occupies a landscape shaped by ancient geology and the coastal processes that have shaped the Keiss Links over millennia.

The broch's double-walled circular construction, typical of its class, would have provided both defensive capability and shelter for its occupants. The sandy, wind-exposed location of Keiss Links presents the characteristic environment of Caithness brochs, perched on the northern coast where these monuments cluster in notable concentration. The structure's survival on this dynamic coastal terrain represents a significant archaeological record of Iron Age settlement patterns in the far north.

Castle Linglas is protected as a scheduled monument under Historic Environment Scotland reference SM540, recognising its importance as evidence of early settlement and the sophisticated architectural knowledge of Iron Age communities in Caithness. The site contributes to our understanding of how these remarkable structures functioned within their local geography and the broader patterns of Iron Age occupation across northern Scotland.
