From Wartime Shelters to Secret Stories
Beyond its towers and grand rooms, Cardiff Castle has a hidden side.
Beneath the castle grounds lie extensive Second World War air-raid shelters, built to protect thousands of people during bombing raids. Elsewhere, lesser-known towers, symbols and spaces reveal stories of everyday life, conflict and creativity.
Exploring these hidden elements adds depth to a visit, showing how the castle has adapted to the needs of the city across centuries.
The WW2 Air Raid Shelters
Hidden inside the Castle’s reconstructed Roman walls are tunnels that the 4th Marquess requested, apparently so he could continue to enjoy hid daily walks despite the Welsh weather. During the war years from 1939 – 1945, the Marquess of Bute volunteered these tunnels for use as an air raid shelter.
When the sirens sounded, almost 2,000 residents and local workers could seek shelter here, protected by the earth banks and layers of masonry above.
The Roman Chariot Corner
Hidden beneath the Castle’s south-east tower, situated opposite one of the remaining sections of Cardiff’s third century AD Roman fort, is an incredible mural made out of cement and plaster, finished in metallic gold paint. Commissioned by Cardiff City Council in the 1980s, the mural depicts scenes from the Roman invasion of the area and conflict with the local Silures tribe.
Following a recent refurbishment, the Chariot Corner is now open to the public and admission is included with a Castle Ticket.
