Dun Carloway is a remarkably well-preserved Iron Age broch on the west coast of the Isle of Lewis, standing to a maximum height of around 9 metres on its north side. Built probably in the first century BC or first century AD, it is a drystone hollow-walled tower with the characteristic intramural gallery, stair, and central courtyard; later evidence indicates intermittent reuse into the medieval period, perhaps as late as around AD 1300. Despite the Pleiades classification, it is not a Roman military structure — brochs lie well beyond the Roman frontier and are indigenous Atlantic Scottish monuments.

The broch sits entirely outside the Roman world, in territory the Romans never occupied; it reflects an indigenous Hebridean elite tradition of monumental residence, status display, and defensible farmstead architecture rather than any imperial military function. Dun Carloway is among the best-surviving brochs in the Western Isles and a key site for understanding Atlantic roundhouse architecture.
The site has been surveyed and consolidated rather than fully excavated; limited investigations have recovered pottery and evidence of secondary occupation, and a 17th-century tradition (recorded by Martin Martin) associates it with use by the Morrisons of Ness as a refuge.

Dun Carloway is classified as a Roman watch tower — a military site in the Pleiades ancient world gazetteer. Roman Britain's archaeology encompasses thousands of sites ranging from legionary fortresses and marching camps to villas, temples and towns.
Several Roman sites lie within a short distance, including Cawdor (186.2 km), Auchinhove camp (243.5 km), Bannatia? (270.5 km). Aubrey Research maps over 2,200 Roman sites across Britain, drawn from the Pleiades ancient world gazetteer.
