Perched like a storybook dream above the wooded slopes of the Taff Valley, Castell Coch is one of Wales's most enchanting sights. This travel poster celebrates that romance - the turreted silhouette of a red-brick castle, the hush of surrounding trees and the soft, late-day light that gives the whole scene a timeless glow. The site itself is layered with history. A medieval fortress once stood here; the present castle, rebuilt in the 19th century in a lavish Gothic Revival style, reads like an architectural fairy tale. Visitors arrive to find narrow bridges, round towers and richly decorated interiors that speak of Victorian imagination. Outside, the valley and ancient woodland invite easy exploration: quiet paths, mossy banks and the sudden reveal of the castle through a canopy of leaves. This poster aims to capture those moments - the instant when you glimpse the castle framed by trees, when the last sun of the day gilds the stone and the air smells faintly of damp earth and wildflowers. The composition uses simplified shapes and layers of flat colour to mirror classic travel art: broad planes of warm ochre, russet and terracotta for the castle, set against deeper greens and olive tones of the surrounding woods, with a pale, misty blue for the distant hills and evening sky. Colour is at the heart of the design. The red of Castell Coch is rendered in rich, velvety tones that suggest both warmth and history. Greens range from deep forest to sunlit sage, giving depth without fuss. A gentle gradient sky shifts from evening gold to cool blue, suggesting that liminal hour when the day feels full of possibility. The whole palette is muted rather than loud - inviting, nostalgic and quietly optimistic. Typography plays a key role in the poster's mood.
