Caerau Fort: Cardiff’s Ancient Iron Age Hillfort and Community Heritage Hub

An Ancient Stronghold Above Cardiff

Caerau Fort is an expansive Iron Age hillfort perched on a hillside in the southwestern suburbs of Cardiff. Archaeological evidence dates the site back more than 6,000 years, making it one of the oldest and largest hillforts in Great Britain. Its earthwork ramparts, though now covered in trees and grass, once enclosed roundhouses and communal spaces, serving as a defensive and social hub for the Silures tribe, who resisted Roman invasion fiercely in this region of Wales.

Archaeological Discoveries and Historical Layers

Excavations at Caerau have revealed a rich tapestry of artifacts, including flint tools, weapons, and jewelry dating back to at least 3600 BCE, alongside Roman pottery from the 1st century AD. These finds illustrate continuous human activity and cultural layers spanning the Neolithic through the Iron Age and into Roman times. The fort’s size and strategic location suggest it may have functioned as a regional capital or key settlement for Welsh clans.

Community Engagement and Heritage Revival

For over a decade, Cardiff University’s Caer Project has worked to preserve Caerau Fort while actively involving the local communities of Caerau and Ely. This initiative has transformed the site into a living heritage resource, where volunteers and schoolchildren participate in archaeological digs, gardening, and reforestation efforts. The project fosters community pride and education, connecting people with their local history and environment.

Natural Setting and Visitor Experience

Approaching Caerau Fort feels like stepping into a countryside oasis within the city’s reach. Surrounded by open fields and woodland, the site offers tranquil walking paths and stunning views across Cardiff’s urban landscape. Nearby lie the ruins of St. Mary’s Church, dating back around 800 years, adding a medieval layer to the historical landscape.

Understanding the Iron Age Lifestyle

The fort’s earthworks evoke the presence of roundhouses and palisades that once sheltered families and communities. Archaeologists emphasize the domestic and social functions of the fort, imagining communal fires, craftwork, and farming life within its enclosure. The discoveries contribute to a fuller understanding of Iron Age society in South Wales, highlighting the importance of horses and ritual practices in this ancient culture.

Preserving a Hidden Gem for Future Generations

Caerau Fort remains a largely hidden treasure within Cardiff, its significance overshadowed by the city’s more famous medieval castle. However, ongoing archaeological work and community involvement continue to reveal its stories and ensure its protection. The site stands as a testament to the enduring human connection to place, history, and nature in Wales.
