Timeline

c. 700BC-100AD

Iron Age

Cliff castles like Redcliff were built during the Iron Age for a range of purposes, which likely changed over time.

2003

Modern day

Redcliff Cliff Castle was listed as a Scheduled Monument in 2003, protecting the site for future generations to learn from and enjoy.

Overview

Projecting west into the Atlantic are the remains of an early Iron Age (c. 2800-2000 years ago) cliff castle. The impressive banks and rock cut ditches are the remains of two sets of ramparts enclosing a defensible crescent shaped interior, with steep cliffs on the seaward side.

These impressive defences may have originally been stone faced and the deeper ditch still has steep faces of exposed cut bedrock. It is likely that the majority of the interior of the monument has now eroded away and only the ramparts and the causeway through the centre remain.

As many as 65 possible cliff castles have been identified in Cornwall, variously interpreted as strongholds to control trade and communication routes, a seat of power for a tribal chief or as ritual spaces between the land and the sea.

Redcliff 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.

Historical Significance

Redcliff Cliff Castle was built over 2,000 years ago during the Iron Age when people built strong defences using earth banks and ditches. These ramparts helped protect a crescent-shaped area on the clifftop. With steep drops to the sea on one side and strong walls on the other, it would have been a great place to keep watch, stay safe and control important resources in the local area.

We’re not exactly sure what cliff castles like this were used for. Some may have been strongholds for tribal leaders, others places for trade or even for rituals linked to the land and sea. Most of the interior of Redcliff has now been lost due to coastal erosion, but the impressive defences and the causeway that once led inside still remain. They offer a glimpse into how people living in Cornwall organised themselves and adapted to living in challenging conditions over two thousand years ago.

Features of Interest

One of the most exciting things you can spot at Redcliff Cliff Castle is the remains of its ramparts, easily identified earth banks and ditches carved through the the rock. These were built over 2,000 years ago, possibly to protect the people who lived here or their resources. The ramparts form a big crescent shape, wrapping around the cliff edge. Even though the sea has washed some of the land away over time, you can still see where the entrance once was and imagine what it might have looked like when it was a busy, important place high above the waves, controlling the land and seascape.

Local Flora & Fauna

Redcliff Cliff Castle isn’t just special because of its history it’s also home to some amazing wildlife. If you’re lucky, you might spot seabirds like fulmars or gulls gliding along the cliff edge. In the fields above, wildflowers like sea thrift and kidney vetch bloom in spring and summer, adding pops of colour to the green grass. Keep an eye out for butterflies fluttering past and maybe even a rabbit or two hiding in the bushes. The salty sea air and open skies make this a great spot for nature lovers as well as history hunters.

How Visitors Can Help

You can help take care of Redcliff Cliff Castle just by being kind to the site and the nature around it. Stick to the paths so you don’t damage the grassy ramparts or wildflowers. If you bring snacks, take any rubbish home with you seabirds and other animals can get hurt if they find plastic or food wrappers. Every small action helps protect this amazing place for the future.

Efforts and Challenges

Looking after Redcliff Cliff Castle isn’t always easy. Because it sits right on the edge of the sea, wind and waves are slowly wearing it away and each year a little more of the land disappears. Experts are working hard to record and protect what’s left, but nature moves quickly.

Volunteers and archaeologists have been helping to understand the site better and share its story with everyone. It’s a race against time, but every visit, photo and conversation helps keep Redcliff’s history alive.
