Wales’ Hidden Castles Beyond Major Attractions
Wales is famous for its castles—Caernarfon, Conway, Caerphilly—but beyond these obvious attractions are dozens of lesser-known castles, ruins, and fortifications that offer spectacular heritage without crowds. These hidden castles tell Wales’ story beyond its most famous names.
This guide reveals Wales’ hidden castles, explaining what makes each special, where to find them, and experiencing Welsh heritage away from tourist crowds.
Understanding Wales’ Castle Heritage
Wales’ castle heritage spans centuries:
Medieval Period (12th-15th centuries): Native Welsh princes and English Marcher Lords built castles across Wales, particularly in contested border areas.
Edwardian Conquest (late 13th century): Edward I’s conquest led to massive castle-building as English kings consolidated control.
Welsh Revolt (early 15th century): Owain Glyndŵr’s revolt led to further castle-building and fortification of Welsh borders.
Tudor Period (16th-17th centuries): Some castles were maintained, others abandoned as defensive needs changed. The rise of artillery made many medieval castles obsolete.
Civil War: Several castles were garrisoned and saw action during the Civil War.
Later Periods: Many castles became romantic ruins, inspiring artists and poets, or were demolished for building materials.
What makes Welsh castles special is their connection to Welsh history and landscape—they’re not just buildings but symbols of Welsh identity, struggle, and survival.

Understanding Welsh Castle Types
Welsh castles fall into several types:
Native Welsh Castles: Built by Welsh princes using distinctive Welsh architectural features like D-shaped towers and stone construction.
Marcher Lord Castles: Built by English kings and lords to consolidate control of Wales, often more elaborate and expensive than native castles.
Earthwork Castles: Motte-and-bailey castles that rely primarily on earthwork defences rather than stone towers.
Stone Castles: Elaborate stone-built castles with towers and curtain walls, often very expensive to build.
Border Castles: Castles located on the Welsh-English border, built to defend against invasion from both sides.
Each type tells a different part of Wales’ history and relationship with England.
Welsh Castle Architecture
Welsh castles share distinctive architectural features:
D-Towers: Distinctive D-shaped towers, particularly common in native Welsh castles.
Stone Walls: Curtain walls of stone, often very thick and substantial.
Towers: Round towers (earlier castles) or square towers (later castles) providing defensive positions.
Gatehouses: Defended gatehouses, often with murder holes for dropping projectiles on attackers.
Great Halls: Large indoor spaces used for gatherings, feasts, and administrative functions.
Chapels: Private chapels within castles for religious services.
These features combined to create distinctive Welsh castle architecture that’s different from English castles, reflecting Welsh building techniques and defensive priorities.
Welsh Castle Photography Tips
Dramatic Locations: Castles like Castell Carreg Cennen and Castell Dinas Emrys have spectacular mountain or coastal locations. Use wide-angle lenses to capture landscape connection.
Ruins: The atmospheric decay of castle ruins, particularly in mist or atmospheric light, makes for excellent photography.
Views: The views from castle earthworks across valleys, mountains, or coasts are spectacular. Use telephoto lenses to capture distant landscapes.
Weather: Overcast or misty days can be better than bright sun for castle photography, creating atmosphere and revealing detail.
People for Scale: Include people in some shots to show the scale of castle remains and their relationship to surrounding landscape.
Welsh Castle Etiquette
Respect Private Land: Many Welsh castles are on private land. Stay on public footpaths and respect boundaries. Don’t climb on walls or enter private areas without explicit permission.
Don’t Touch Artifacts: Don’t touch or remove any artifacts, stones, or other items from castle sites. They’re fragile heritage.
Keep Noise Down: Many castle sites are peaceful and contemplative. Keep voices down and respect other visitors’ experience.
Safe Exploration: Castle ruins can be unstable. Stay on marked paths, don’t climb on walls or masonry, and be cautious of uneven ground.
Seasonal Welsh Castle Visits
Spring: Good weather for castle exploration, with wildflowers in castle grounds and lush green vegetation.
Summer: Best weather, but some sites can be crowded. Early morning offers quieter periods and best light for photography.
Autumn: Beautiful autumn colours in castle grounds, cooler temperatures, good photography light. Some sites can be muddy after summer rain.
Winter: Quietest time, but days are short and weather can be harsh. Castle ruins are atmospheric in winter light and mist. Some sites may be less accessible.
