Salvete, readers and history-lovers!
Welcome to The World of Isle of the Blessed!
In this seven-part blog series, we’re going to be taking a look at the research that went into my latest historical fantasy release, Isle of the Blessed, Book IV in the #1 bestselling Eagles and Dragons series.
Over the next few weeks, I’ll take you on a journey through the world of early third-century Roman Britain in which we will look at the history, archaeology, and historical events that took place during this pivotal time in the Roman Empire in which the book is set.
In this first post, we’re taking a closer look at a site that is well-known to Arthurian enthusiasts: the hillfort of South Cadbury Castle.
At the very south ende of the chirche of South-Cadbyri standith Camallate, sumtyme a famose toun or castelle… The people can tell nothing ther but that they have hard say that Arture much resorted to Camallate. (John Leland, Royal Antiquary, 1532)
The hillfort of South Cadbury Castle in Somerset, England, is one of the major locations in Isle of the Blessed. However, most people are familiar with it as a site with strong Arthurian associations. As such, its importance and role is hotly debated.
Though Isle of the Blessed is not a story of King Arthur and the Knights of the Round Table, it is difficult not to speak of this important Iron Age site without discussing the Arthurian connection.
Was South Cadbury Castle the power centre of the historical Romano-British warlord, or dux bellorum, we know as ‘King Arthur’? Was this the actual site of what has come to be known in the popular imagination as ‘Camelot’?
I’ve always been a strong proponent of the theory that there was in fact, an historical ‘Arthur’ who formed the factual basis for all the legends we love and cherish. So, when I look at sites such as South Cadbury, I do so with that in mind. However, that doesn’t mean that I accept a site’s association with Arthur on faith alone.
I know this site pretty well – as I studied it and wrote about it as part of my Master’s dissertation entitled “Camelot: A look at the historical, archaeological, and toponymic evidence for King Arthur’s Capital”. As part of this, I looked at three of the main candidates for Camelot that had been put forward at the time – Wroxeter (Roman Viroconium), Roxburgh Castle (in the Scottish Borders), and South Cadbury. There is a copy of the dissertation hidden somewhere in the stacks at the St. Andrews University library in Scotland.
South Cadbury Castle is also where I cut my teeth as an archaeologist as part of the South Cadbury Environs Project team for a couple of seasons under the leadership of Richard Tabor. This was a wonderful experience that helped me to get up close and personal with the site I had studied for so long – I dug test pits, got into bigger trenches in which curious cows came to watch what I was doing, carried out geophysical surveys with a magnetometer, and found some curious objects such as a bronze dolphin that formed the handle of a Roman drinking cup.
Most of all, I was given the chance to spend more time on this amazing, and yes, magical, landscape.
And a couple years ago, when doing research for Isle of the Blessed, I returned to South Cadbury where I also filmed a mini-documentary on the site (coming out later this year!).

Before I give my thoughts on wandering the slopes of South Cadbury Castle, we should have a look at what it actually is.
South Cadbury Castle is not the late medieval castle with banners flying from tall towers that make up our usual image of Camelot. It is a 500 foot high Iron Age hillfort located in the pre-Roman era lands of the Durotriges. Occupation of the site began in the Neolithic period and it went through various stages of occupation from the 5th century B.C. onward.
By the time of the Roman invasion of Britain, it had four massive defensive ramparts with an inner area of about 18 acres. Access to the top was by two entrances, one to the north-east and the other, larger one, to the south-west. The Iron Age occupation of the site came to a violent end around A.D. 43 when Vespasian stormed the southern hillforts of Britannia.
The Romans made little use of the site, though there have been some theories that it was used as a Roman supply station. This theory is explored in Isle of the Blessed and the Eagles and Dragons series. In the 3rd and 4th centuries, there was renewed activity with visits being made to a Romano-Celtic temple that was built on the site.

During excavations, a bronze letter ‘A’ was found that some believe belonged to this temple, which was perhaps dedicated to Mars, or some other deity.
However, when it comes to South Cadbury Castle, the periods that have always drawn me to it are the 5th and 6th centuries A.D. This period of the site is known as the ‘Arthurian’ period, and it is at this time, after Rome’s legions had left the island, that the archaeology shows a massive refortification of the hillfort.

Though it is much debated, South Cadbury’s association with the Arthurian period stems not just from hearsay and folklore. It has the archaeological evidence to back it up.
There have been a few big excavations of the hillfort over the years, but the biggest of all took place in the late 1960s and was headed by Professor Leslie Alcock. Professor Alcock and his team discovered evidence for a large scale occupation and refortification of the hillfort, during the Arthurian period, which showed repaired defences, including a strong gatehouse at the south-west entrance, and most importantly, several buildings, including a kitchen and a large timber hall on the fort’s high plateau.
The discovery of post holes reveals a finely-built timber hall that was on a large scale, measuring about 63×34 feet. This hall would not have been the great castle hall of late medieval romance, but rather something like the timber drinking halls of the period, more like to the Golden Hall of Meduseld, the seat of King Theoden in Lord of the Rings.
Another very telling discovery at Cadbury Castle was the large quantity of Mediterranean pottery that dates to the Arthurian period of activity. This is the same pottery type that was discovered at Tintagel Castle in Cornwall, a site that also has strong Arthurian associations. One might think that shards of pottery from wine, olives and olive oil might be pretty mundane, but they anchor the sites strongly in the period, and also show that someone of importance was associated with the site. Not everyone could afford to import such things through trade.
The refortification of the hillfort during the Arthurian period was on a massive scale, and would have required many resources and men to hold it. South Cadbury castle was, in a way, on the front lines of the British struggle against the invading Saxons, and would have been well-placed to meet the Saxons as they advanced westward.
Based on the refortification, and evidence of the gatehouse that linked the ramparts running over the cobbled road at the south-west corner, this place was likely the base for an army that was large by the standards of the period. It may have been the site of the court of the dux bellorum, or the historical Arthur.
