Approaching Castle Dore from the Saints’ Way, the earthworks rise gently from the ridge above the tributaries of the Fowey. At first sight the site looks simple: a ring of banks and ditches enclosing a grassy interior, the sort of place a dog runs happily while its owner pauses to take in the view. Yet the ground here carries two parallel histories. One is archaeological, measured in ramparts, pottery and excavation trenches. The other is legendary, shaped by medieval storytellers who placed kings and lovers among these banks. Walking the circuit, it becomes clear how the two narratives have become intertwined.
Castle Dore is a small multivallate hillfort, one of a rare class of Iron Age settlements usually found in the south‑west and the Welsh Marches. These sites, typically between one and five hectares, were enclosed by two or more closely spaced earthwork circuits. At Castle Dore the inner rampart and ditch form a near‑circular enclosure, while a second, mainly concentric outer rampart creates a broader defensive ring. On the eastern side the earthworks diverge to form a more complex entrance annexe, a feature that becomes more legible as you walk the line of the banks.
The archaeological record places the first construction of the hillfort in the 5th–4th centuries BC, based on ceramics recovered during the 1936–37 excavations by C. A. Ralegh‑Radford. After a period of abandonment, the entrance was remodelled in the 4th–3rd centuries BC. Inside the enclosure, Radford uncovered the stake holes of round houses and several four‑ to six‑post structures interpreted as raised granaries. (see image below from Radford, Ralegh & Swanton, Michael – Arthurian Sites in the West ) The pattern suggests a long sequence of rebuilding and replacement, the sort of steady occupation typical of high‑status Iron Age settlements. Two oval structures may represent later, possibly Romano‑British activity, though the pottery suggests the site was largely abandoned before the Roman period. Finds included imported glass bracelets and a glass bead, small but telling indicators of trade and status.
That is the archaeological Castle Dore: a defended Iron Age settlement, occupied in phases, with evidence of domestic life, storage, and long‑distance connections. But as you stand on the inner rampart and look across the interior, it is easy to see why later generations imagined something more. The hillfort was first mentioned in writing by William Worcester in 1470, long after its Iron Age inhabitants had gone. By then, the site had already entered local tradition as the home of King Mark, the ruler who appears in the Tristan and Iseult stories. Medieval writers placed Mark’s palace, ‘Lancien’, somewhere in this district, and Castle Dore, with its commanding position and impressive earthworks, became the favoured candidate.
The association was strengthened by the nearby inscribed pillar commemorating Drustans, often linked to Tristan. The inscription itself is early medieval rather than Iron Age, but its presence in the landscape helped bind the legend to the hillfort. For centuries, visitors have walked these banks imagining Mark’s court, Tristan’s exile, and Iseult’s sorrow set against the Cornish hills. The legend has become part of the site’s identity, even though the archaeology points firmly to a much earlier origin.
Walking the ramparts today, the contrast between the two narratives is striking but not contradictory. The Iron Age settlement is real, datable and well understood. The medieval legend is not evidence, but it is part of the cultural life of the place, shaping how people have viewed Castle Dore for more than five hundred years. The hillfort’s earthworks, impressive even in their worn state, provided a ready stage for storytellers seeking a royal residence. The landscape itself encouraged the connection.
In the end, Castle Dore is both things at once: an Iron Age hillfort with a clear archaeological sequence, and a site that later generations adopted into the Tristan and Mark tradition. The legend does not explain the earthworks, but it does explain why the site has remained prominent in local memory. As you complete the circuit and descend back towards the Saints’ Way, the two histories sit comfortably together. The banks belong to the Iron Age; the stories belong to the medieval imagination; and the experience of walking the site today is shaped by both.
