Wales is often referred to as the “Land of Castles”—and rightly so. With over 600 castles nestled across its hills, valleys, and coastlines, it boasts more castles per square mile than any other European country. Ranging from crumbling ruins to fully restored medieval fortresses, each castle holds its own tale to tell.

For newcomers to Wales, these castles offer much more than mere photography spots. They provide an insight into Welsh history, folklore, and culture. Some murmur of grand battles and royal uprisings. Others resonate with romantic legends and long-hidden secrets. Whether you’re walking along ancient ramparts or peering through arrow slits over misty hills, exploring the castles of Wales feels like stepping into a living storybook.

If you’re planning your first visit to Wales, exploring at least a few of its famous fortresses is a must. This guide will help unearth the very best castles—each one with its unique allure.

Caernarfon Castle: The Royal Stronghold

Dominating the Menai Strait in North Wales, Caernarfon Castle stands as a towering symbol of power and splendour. Constructed by Edward I in the late 13th century as part of his “Iron Ring” of castles to conquer Wales, its polygonal towers and striking architecture distinguish it from other Norman styles.

Beyond its formidable appearance, Caernarfon is deeply intertwined with royal tradition—it’s where the Prince of Wales is invested, including Charles in 1969 and recently, William in a symbolic ceremony.

Why visit:

• UNESCO World Heritage Site designation
• Stunning medieval architecture and interactive displays
• Breathtaking views of the Menai Strait from the battlements

Caernarfon is a fixture on any itinerary for Wales—and an excellent starting point for exploring Snowdonia and Anglesey.

Conwy Castle: A Fairytale Fortress

Conwy Castle appears as though it’s been plucked straight from a storybook. With its eight enormous towers and dramatic seaside setting, it’s one of the best-preserved medieval castles in Britain. Like Caernarfon, it was built by Edward I and is part of the UNESCO-listed collection of Welsh castles.

Inside, the castle’s concentric design, spiral staircases, and fortified walkways provide endless exploration opportunities. From the upper walls, enjoy panoramic views of the town and estuary below.

Highlights include:

• A complete circuit wall walk offering sea and mountain vistas
• Atmospheric rooms and ancient great halls
• Proximity to Conwy’s charming town centre and harbour

For families, it’s a place where imaginations can soar—and for history enthusiasts, it’s a dream realised.

Pembroke Castle: Birthplace of a Monarch

Situated on a rocky promontory beside a tidal river, Pembroke Castle is one of the most complete Norman castles in the UK. It’s also the birthplace of Henry VII, the first Tudor king—a fact that endows it with significant importance in British royal history.

Visitors can climb the massive round keep, explore dimly-lit passageways, and even descend into a vast subterranean cavern beneath the castle. The expansive grounds and scenic location make it a standout destination in South Wales.

Why it’s special:

• Superb historical interpretation and family-friendly tours
• Re-enactments, events, and summer performances
• Easy access from Tenby and the Pembrokeshire Coast Path

This isn’t just a stop—it’s an immersive experience, especially for those travelling with children or those passionate about history.

Harlech Castle: The Hilltop Sentinel

Dramatically perched on a cliff above Cardigan Bay, Harlech Castle commands attention. Another Edwardian fortress, it is famed for withstanding sieges during the Wars of the Roses and inspiring the stirring anthem Men of Harlech.

The approach to the castle is part of the adventure, with a steep drive or walk rewarded by panoramic views of both sea and mountain. Inside, the towers and gatehouses provide insight into its once-formidable defences.

What to expect:

• Stunning vistas across Snowdonia and the Llyn Peninsula
• An engaging visitor centre with interactive history displays
• Fewer crowds than other major castles

It’s a favourite for photographers, walkers, and anyone seeking that “on top of the world” feeling.

Castell Coch: A Victorian Fantasy

Nestled in the wooded hills above Cardiff, Castell Coch (meaning “Red Castle”) is a fairytale vision of turrets, drawbridges, and Gothic revival fantasy. But don’t be deceived by its Disney-like appearance—this castle has layers of history dating back to the 13th century.

What you see today was reimagined in the 19th century by architect William Burges for the Marquess of Bute. It’s filled with decorative arts, ornate ceilings, and whimsical details, making it one of the most unique castles in Britain.

Reasons to visit:

• Romantic architecture with artistic interiors
• A short drive or cycle from Cardiff city centre
• Woodland walks and picnic spots nearby

It’s the perfect blend of history, fantasy, and nature—ideal for a leisurely afternoon.

Raglan Castle: A Renaissance Treasure

Raglan Castle, located in Monmouthshire, is unlike most other medieval Welsh castles. With its Renaissance embellishments and decorative towers, it offers a more refined, palatial experience than the typical austere fortress.

Though partially ruined following the English Civil War, it retains grandeur through its symmetry, great tower, and elegant stonework. Visitors can explore its formal gardens, climb the winding staircases, and gaze out over the Welsh countryside.

Why include it in your itinerary:

• A beautiful mix of defensive architecture and Renaissance elegance
• Less crowded and off the typical tourist trail
• Close to Abergavenny and Brecon Beacons National Park

It’s a refreshing departure from the rugged military castles—and perfect for those who relish peaceful discovery.

Dolbadarn Castle: A Castle of the Landscape

Though smaller and more ruined than others listed, Dolbadarn Castle near Llanberis boasts one of the most spectacular natural settings. Built by the native Welsh prince Llywelyn the Great, it sits at the foot of Snowdon, overlooking Llyn Padarn.

The round tower remains largely intact and once served as a royal prison. Today, it’s a tranquil, haunting place that speaks to a different chapter in Welsh history—one of native resistance and mountain strongholds.

Worth it for:

• A short scenic hike with stunning views
• Connection to the native Welsh royal legacy
• Near Llanberis, the Snowdon railway, and walking paths

It’s atmospheric, raw, and perfect for a contemplative pause during a day of exploration.

Top Tips for Castle Hopping in Wales

Exploring multiple castles in a single trip is not only doable—it’s delightful. Here’s how to make the most of it:

Get a Cadw pass: Cadw oversees many Welsh heritage sites. A visitor pass grants access to dozens of castles and monuments.

Plan your route: While Wales is compact, roads can be narrow and winding. Cluster castle visits by region.

Wear sturdy shoes: Expect uneven paths, stairs, and plenty of walking.

Time your visits: Early mornings or late afternoons offer the best light (and fewer crowds).

Check for events: Many castles host summer jousts, medieval fairs, and re-enactments—great fun for all ages.
