Largin Castle – Iron Age Hillfort

Largin Castle

Hidden deep in woodland above the River Fowey is what remains of Largin Castle. It sits on the top of a steep ridge that towers above the Glynn Valley, and is the perfect spot for a defensive structure. But Largin was no Roman outpost or ‘motte and bailey’ affair. This ‘castle’ was built in the Iron Age, around 800BC – 43AD.

Iron Age hillforts remain a dominant and often striking feature in our landscape, even 2000 years after they were constructed. Largin is just one of around 3,300 hillforts that can still be found across Britain. In fact, most hillforts are found in the South West of England, in Wales and Scotland. Around eighty have been identified in Cornwall alone, dating from various periods of prehistory and the county also has a number of cliff castles and tor enclosures such as the one at Helman tor. Cornish hillforts tend to be a bit smaller than those found in other parts of the country.

Largin Castle covers an estimated 4 acres. It has triple ramparts and ditches which surround an oval central enclosure. In places these ramparts are as much as 3.5m high.

Ethnologist J. Forde-Johnston describing hillforts as an “eloquent testimony of the technical ability and social organization of the Iron Age peoples.” And the effort taken in their construction is impressive and thought-provoking. Ann Preston-Jones, Historic England’s Heritage at Risk Officer for Cornwall described this site as being “arguably of national importance”, despite this it remains unscheduled. And as far as I can establish there has also been little or no study of the site either.

The actual purpose of hillforts is up for debate. Indeed the term hillfort is a catch-all phase often used to describe any kind of enclosure or earthworks on the top of a hill or similarly high feature. And the term ‘fort’ also assumes some kind of defensive purpose but that may not have always been the case. In fact each individual ‘hillfort’ may simply have been built for it’s own specific purpose or need. Many were defensive, of course, taking full advantage of the contours of the landscape, but some of these structures may have had more ceremonial or ritualistic uses. An idea that has seen little serious investigation.

The outline of the hillfort is quite obvious from a distance, highlighted by the older trees amongst the evergreen trees of the forestry plantation that surrounds it.

Further information about Largin Castle is very scant. So if anyone is able to add to this I would very much appreciate you getting in touch.

And I do find it ironic that the East Largin Viaduct (c1855) directly below the Largin Castle is scheduled while the hillfort is not. It remains unprotected by the law. (See article on Cornwall’s defenceless monuments below.)

Getting there

Finding the castle isn’t difficult it is very well marked on the OS map.

I walked up the hill from Two Watersfoot bridge (beside Trago), under the railway line and entered the plantation via the gate near the top of the hill. From there you just follow the track down through the valley and up the other side. You will see a track leading off to the right, this takes you to the castle.

Since writing this I was contacted by someone online who felt so strongely about the lack of protection for this site that they created a Wikipedia page for it!

  1. Thanks for this-we need to understand and celebrate all these early sites which suggest a complex and vibrant society long before ‘ history’ says it was present in Cornwall
