History

Timeline

2800-2000 years ago

Iron Age

Recent interpretations based on ceramics found at the site suggest the site was occupied as early as the 5th-4th centuries BC. Various arrangements of post holes indicate replacement structures and several phases of development, including remodelling of the entrance.

43AD onwards

Romano-British Period

The site was thought to have been abandoned before the Roman period begins in 43AD, however, two oval structures that could possibly be Romano-British suggest activity at the site during the Roman period.

600's CE

Early Medieval Period

Fort falls out of use as settlements shift to new locations.

1936

Excavation

Excavations uncover evidence of Iron Age and later occupation including glass beads and fragments of pottery.

1956

Modern Day

Castle Dore designated a Scheduled Monument, protected by law for future generations to learn from and enjoy.

Overview

Castle Dore sits along a ridge, running from Fowey to Lostwithiel, providing views to the southwest across the Fowey Estuary and eastwards to the broadly contemporary Black Head Cliff Castle. If the two sites were both occupied at the same time, they would have been aware of each other and likely shared some resources.

On the nearby original 1964 interpretation panel, Castle Dore is dated to the “3rd to 1st centuries BC” however more modern analysis of pot sherds found in the 1930’s excavation provides an earlier, 4th or possibly 5th century BC date for its construction.

Castle Dore is a significant example of an Iron Age hillfort, built around 300 BCE. It served as a stronghold for the local tribes, controlling the land around the Fowey River. Archaeological excavations revealed traces of defensive ramparts and gateways. The site was also linked to the legendary figure King Mark of Cornwall, placing it in the broader context of Arthurian mythology. The site was excavated in the 1930’s by Raleigh Radford who found evidence for settlement in the interior of the monument and between the ramparts.

Historical Significance

Although today we call it a castle or fort, the purpose of hillforts is unclear, and at different times the monument may have had different uses. In the 1930’s the site was partially excavated by Raleigh Radford who believed he had found the “royal hall of King Mark” who is supposed to have lived in the Early Medieval Period and was mentioned in the legend of Tristan and Iseult. However, more modern dating of the finds has suggested the earthworks to be much older.

The ramparts probably had a wooden palisade wall on top making access across the two steep ditches and banks incredibly difficult. The entrance could have been remodelled several times with banks and ditches being built and dismantled. This reorganisation is common at Hillforts, where defences could become complex obstacles to navigate. At Castle Dore there likely would have been a gate at the entrance, possibly to help keep their livestock such as cattle, goats and pigs safe within the ramparts, and any unwelcome visitors out.

As a settlement, this defendable position is an obvious choice as a centre of power for a tribal chief, a secure place to store the excess from the harvest, as well as livestock that provides the people in the Iron Age with enough to eat during the winter.

In the centre of the monument is a clear, flat enclosed area where round houses have been found, perhaps an entire village lived within the ramparts.

It has also been suggested that hillforts were communal places, built on tribal boundaries where meetings were held between leaders, possibly for trading, making important decisions or ritual purposes with very little defensive or militaristic purpose. It could be that different hillforts were built for various reasons, and that those purposes changed through time.

Castle Dore has a a rich history of research, including excavation. A review of the 1930’s excavations published in Cornish Archaeology in 1985 provides detail and discussion of three key phases of occupation at the site. In its initial 4th Century BC construction, the hillfort included the two sets of ramparts we see today, with the outer earthwork swinging outwards at the entrance to create a second enclosed space. Historic records suggest a significant third enclosure which has now vanished from the ground but may be represented in the geophysical survey anomalies recorded by the Monumental Improvement Project. Houses were built and their foundations, cut through the shillet, and post holes dug to hold the roof have been across the excavated trenches, but their dating cannot be assigned to any specific period due to a lack of finds or clear stratigraphy.

Following a period of abandonment which studies have shown was common practise at similar sites, where evidence of cycles of occupation and abandonment contribute to archaeologists being able to build a clearer timeline of construction and alteration than sites which have longer periods of occupation.

The third phase at Castle Dore is defined by a strengthening of the ramparts, with the inner bank heightened and the ditch recut as well as a substantial timber gate, with a possible bridge built at the entrance. More houses possibly date to this later phase, and much of this archaeology has been affected by later ploughing of the interior.

The fourth phase of Castle Dore’s use included some minor alterations and heightening to small areas of ramparts, construction of a roadway, two oval structures and a new style of building, where post holes has been packed tightly with edge set slabs of stone. These strengthened post holes did not form an obvious arrangement on their own, but when considered with other post holes which may have had packing stones since disturbed through packing were the basis of the original ‘palace of King Mark’ interpretation. However, a modern interpretation based on comparisons with the widely excavated Danebury or Moel y Gaer has suggested these four and six post structures were more likely of Iron Age origin, not a later, early medieval phase of use and may represent the remains of a granaries.

Other possible interpretations of the complex of post holes are stake walled houses, leaving the possibility for a much more complex building sequence with frequent replacement of structures.

Although the modern interpretation of the site puts the significant building activity in pre-history, there are several features from later date at the site, including medieval quarrying at the inner gate, and possible lazy beds to the north of the outer bank.

 

Myths and Legends

Echoes of love and legend at Castle Dore

Castle Dore isn’t just rich in history – it’s steeped in legend too. One of the most famous tales linked to the site is the story of Tristan and Iseult, a tragic love story that has echoed through Cornish folklore for centuries. According to the legend, Castle Dore was the seat of King Mark, Tristan’s uncle. Tristan was sent to Ireland to bring back the beautiful Iseult to marry King Mark, but the two accidentally drank a love potion and fell hopelessly in love. Their forbidden love led to heartbreak and betrayal, with Castle Dore serving as the backdrop for this romantic tragedy.

Some say you can still feel the sorrow of Tristan and Iseult in the air at Castle Dore. On a quiet day, when the wind whispers through the trees, visitors might hear echoes of the star-crossed lovers. This ancient hillfort, perched above the Fowey Valley, certainly feels like the kind of place where legendary tales would unfold.

Another myth linked to the site is that of King Arthur. As with many ancient sites in Cornwall, local folklore often ties them to the legendary king. Some believe that Castle Dore may have been the site of important meetings between Arthur and his knights, or perhaps even one of his lesser-known battle sites.

These captivating stories, woven into the fabric of Castle Dore, add a touch of mystery and magic to the site, making it a place where history and legend walk hand in hand.

Features of Interest

Castle Dore is a fascinating historical site, known as one of the best-preserved Iron Age hillforts in Cornwall. Perched high on a ridge, it offers views over the lush Fowey valley below. Its circular shape, consisting of two concentric ramparts, hints at its use as a defensive structure. Archaeologists believe it was a powerful stronghold during the late Iron Age. The site may have also served as a political or social gathering place, given its prominent location. Visitors today can still see the impressive earthworks that once protected the settlement from potential invaders.

Local Flora & Fauna

Castle Dore is surrounded by a variety of native plants and wildlife, typical of Cornwall’s rugged landscape. The site is home to hardy grasses, wildflowers like foxgloves and gorse bushes that provide bursts of colour in the warmer months. Local trees, including oaks and hazel, form a natural boundary around the hillfort. Wildlife also thrives here: songbirds nest in the trees and if you’re lucky, you might spot a buzzard soaring overhead. The grassy areas attract insects like butterflies and bees, while rabbits and other small mammals often hop through the undergrowth.

How Visitors Can Help

When visiting Castle Dore, you can help protect this ancient site by staying on marked paths to avoid damaging the earthworks. Please take any litter home with you and refrain from disturbing the wildlife that calls this area home. Respect the history by not climbing on the ramparts or moving any stones. Your care and consideration will ensure Castle Dore remains preserved for future generations to explore and enjoy.

Efforts and Challenges

Conserving Castle Dore, with its ancient Iron Age earthworks, is no easy task. Erosion, caused by grazing animals and visitor foot traffic poses a significant challenge. Over time, the ramparts have been worn down by rain, wind and foot traffic from visitors. Preservation efforts focus on managing vegetation growth, which can damage the fragile earthworks and carefully monitoring the site for any signs of deterioration.
Local conservation teams and volunteers work diligently to maintain the site, balancing the need to protect it with allowing public access. One of the ongoing challenges is preventing further erosion while encouraging visitors to enjoy and learn from this historic landmark. Through careful management and awareness-raising, Castle Dore continues to be preserved for future generations, ensuring its fascinating history remains intact.

In 2023 Cornwall National Landscape’s Monumental Improvement Project carried out conservation repairs and partial excavation to eroded sections of the ramparts. Read more about the repairs in the summary report in the ‘Dig In’ section at the bottom of this page.
