Kastel Als Karvran
Perched high above the sea near Illogan, Carvannel Cliff Castle is one of Cornwall’s ancient promontory forts. Even though not much remains, its clifftop location tells a story of people living and defending this dramatic stretch of coast over 2,000 years ago.
Carvannel Cliff Castle (AKA Crane Castle) sits along the rugged north coast of Cornwall between Godrevy and Portreath. Built during the Iron Age, between 800 BC and 43 AD, it’s what archaeologists call a promontory fort, a defensive settlement that used the natural protection of the cliffs, with extra ramparts built across the narrow landward side. These types of forts were often used for safety and as a place to live, especially in times of tension. While there’s little visible today, the site’s location offers sweeping views and a sense of why people might have chosen this spot to build their home and protect their community.
Carvannel Cliff Castle was part of Cornwall National Landscape’s A Monumental Improvement Project, which aimed to ensure that 40 scheduled monuments across Cornwall National Landscape were better protected, identified and enjoyed by a wider range of people. Between 2022 – 2025, the Project delivered conservation repairs, installed new heritage interpretation signage, ran a range of community volunteering events and developed new website resources. The Project was primarily funded thanks to The National Lottery Heritage Fund, with support from our other partners – Cornwall Council, Historic England, The National Trust, Cornwall Heritage Trust and Cornwall Archaeological Society.
Though smaller and less well-preserved than other cliff castles in Cornwall, Carvannel is still an important reminder of Iron Age life. Its position shows how local communities made use of the land’s natural defences to guard against attacks. It also forms part of a wider network of similar forts across the Cornish coast, helping us piece together how people lived, worked and protected themselves thousands of years ago. Today, it stands as a quiet but powerful link to Cornwall’s deep past and a site we must continue to care for.

Although little survives above ground at Carvannel Cliff Castle, its hidden features are still important. The shape of the headland and the likely remains of man-made ramparts mark it out as a classic Iron Age promontory fort. These kinds of forts used the steep cliffs as natural defences, with ditches and banks added across the landward side. Even without visible walls, the landscape holds clues from soil changes to buried structures that could tell us more about life here over 2,000 years ago.
Carvannel Cliff Castle sits within a wild coastal landscape, rich in nature. The cliffs and heathland are home to hardy plants like gorse, heather and thrift.
You can help look after Carvannel Cliff Castle just by being a thoughtful visitor. Stick to the paths to avoid damaging the ground and try not to disturb any plants or nesting birds. There aren’t many visible remains, but the site is still really important. Taking litter home and keeping dogs under control also helps protect both the landscape and the wildlife that lives here. Every little bit of care makes a big difference.
Carvannel Cliff Castle might look quiet, but looking after it takes work. Erosion from wind and rain slowly wears away the cliffs and visitor footfall can add pressure to the fragile ground. Because not much survives above the surface, it’s easy for people to miss how important the site is. Local heritage teams are working to monitor its condition and raise awareness, but protecting a site like this with no fences or signs is always a challenge.
Carvannel Cliff Castle becomes Kastel Als Karvran in Cornish.
It means kastel – castle, als – cliff, karvran – crow fort.
