Crosskirk Broch
Crosskirk Broch is a prehistoric Iron Age tower located on the far north coast of Caithness, Scotland, sitting close to the shoreline of the Pentland Firth near the small settlement of Crosskirk. It is one of the best-preserved examples of a broch in the north of Scotland, representing a remarkable survival of a type of drystone hollow-walled roundhouse that was built across northern and western Scotland roughly between 100 BC and AD 100. Brochs are unique to Scotland and are considered among the most sophisticated stone structures produced by prehistoric European peoples without the use of mortar. Crosskirk Broch stands as a testament to the ingenuity and architectural ambition of the Iron Age communities who inhabited this wind-scoured coastal landscape over two thousand years ago.
The broch itself survives to a height of around one and a half metres in most sections, though its foundations, wall thickness, and circular ground plan are clearly legible to the visitor. Like all brochs, it was constructed with a double-wall technique — an inner and outer skin of stone with a hollow gap between them, through which internal staircases would have risen to upper galleries. The entrance passage remains visible, as do the characteristic features of a well-engineered Iron Age structure: door-check rebates, a guard cell, and the massive drystone masonry that has endured millennia of Atlantic exposure. The walls are several metres thick at the base, and the interior diameter is substantial enough to have accommodated a complex, multi-storey living space for an extended family group or small community. Excavations at the site in the 1960s revealed evidence of occupation and associated domestic structures surrounding the broch tower itself.
What makes Crosskirk particularly atmospheric is its setting. The broch stands on a low headland just above the rocky shoreline, with the grey waters of the Pentland Firth visible beyond and, on clear days, the hills of Hoy on Orkney forming a silhouette on the northern horizon. The grass around the ruins is cropped short by sea winds and sheep, and the sound of waves breaking on the nearby rocks is a near-constant companion. Gulls wheel overhead and the salt air is palpable. There is no visitor centre, no information hut, no ticket booth — simply the ancient stones set into the coastal turf, managed by Historic Environment Scotland and freely accessible. The sense of unmediated contact with deep prehistory is powerful here, enhanced by the remoteness of the location.
Nearby, within easy walking distance along the coast path, stand the ruined walls of St Mary's Chapel at Crosskirk — a small Romanesque chapel dating to the twelfth century, which adds a second distinct layer of historical interest to the immediate area. The chapel is roofless and atmospheric, its simple nave and chancel arch suggesting a medieval community that worshipped in this remote spot long after the broch builders were forgotten. Together, the broch and the chapel span well over a thousand years of human occupation at this particular stretch of coastline, making it an unusually rich site for such a quiet and overlooked location.
The surrounding landscape is the wide, flat, treeless terrain of central and northern Caithness — a county that has more in common geologically and culturally with Orkney than with the rest of the Scottish Highlands. The coastline in this area is rugged, with flagstone outcrops and sea-worn cliffs punctuating the grassy clifftop paths. The village of Reay lies a few kilometres to the east, and the Dounreay nuclear power station — now being decommissioned — is visible along the coast in that direction, creating a peculiar visual juxtaposition of prehistoric monument and twentieth-century technological landmark. To the west, the coast continues toward Strathy and ultimately to Thurso, the largest town in Caithness, which is about fifteen kilometres to the east.
Access to Crosskirk Broch is straightforward for those with a vehicle. The site is reached via a minor road that leads north off the A836 coastal road between Thurso and Bettyhill, signposted for Crosskirk. A small parking area is provided at the end of the track, from which a short walk of perhaps five minutes across coastal grassland brings the visitor to the broch and chapel. The path is generally firm underfoot, though it can be muddy after wet weather, and the terrain is slightly uneven around the monument itself. There are no facilities on site. The site is open year-round and entry is free. The best time to visit is from late spring through early autumn, when the weather is most clement and daylight hours are long — midsummer in Caithness brings near-continuous daylight, making evening visits especially memorable.
One of the more intriguing aspects of Crosskirk Broch is how little it is visited relative to its quality and significance. While brochs like Mousa in Shetland or Dun Carloway in the Outer Hebrides draw considerable tourist traffic, Crosskirk remains largely unknown outside of archaeology enthusiasts and dedicated heritage travellers. This obscurity is part of its charm. The combination of a well-preserved prehistoric monument, a medieval chapel, a dramatic coastal setting, and the complete absence of crowds makes it one of those quietly extraordinary places that rewards those willing to venture off the main tourist routes of the Scottish north. For anyone travelling the north coast between Thurso and the Flow Country or taking the North Coast 500 route, a brief detour to Crosskirk is among the most worthwhile stops along the entire journey.
