11 Castles In Cornwall To Visit

Cornwall, with its dramatic coastline, rugged moors, and rich history, is one of the UK's most captivating holiday destinations. Beyond its beaches and scenic walks, the county is also home to a number of striking and historic castles, each offering a unique glimpse into the past. Whether you're a history buff, an architecture enthusiast, or simply seeking new places to explore, these Cornish castles provide unforgettable experiences. From medieval strongholds to romantic ruins, here are 11 of the best castles in Cornwall you won’t want to miss.

1. Tintagel Castle

Arguably the most iconic Cornwall castle, Tintagel Castle is steeped in legend and mystery. Perched dramatically on the North Cornwall coast, this medieval ruin is famously linked to the legend of King Arthur. Cross the modern footbridge to explore the castle ruins, cliff-top views, and Merlin’s Cave below. It's a must-visit for anyone interested in Arthurian lore or breathtaking scenery.

2. St Michael’s Mount

Set on a tidal island off the coast of Marazion, St Michael’s Mount is a magical place combining natural beauty with historical intrigue. The castle, still home to the St Aubyn family, has evolved from a medieval priory into a grand residence. Visitors can walk across the causeway at low tide or take a short boat trip to explore the gardens, fortress, and panoramic views.

3. Launceston Castle

A classic motte-and-bailey castle, Launceston Castle dates back to the Norman conquest. Its strategic hilltop position once served as the gateway to Cornwall. Climb the keep for sweeping views over the town and surrounding countryside. It’s one of the lesser-known but historically significant places to visit in Cornwall.

4. Pendennis Castle

Located near Falmouth, Pendennis Castle is one of Henry VIII’s finest coastal fortresses. Built to defend against invasion, it played a role in both World Wars. Today, it offers interactive exhibitions, family-friendly events, and sweeping views of the Fal Estuary. A visit here brings Cornwall’s military history vividly to life.

5. Restormel Castle

Nestled in a lush valley near Lostwithiel, Restormel Castle is a well-preserved 13th-century circular fortress. Once a luxurious residence for the Earls of Cornwall, it now stands as a striking ruin surrounded by rolling countryside. It's particularly beautiful in spring, when wildflowers bloom along the outer walls.

6. St Catherine’s Castle

Overlooking the Fowey Estuary, St Catherine’s Castle was built by Henry VIII to defend against French and Spanish invasions. Though smaller in scale, it offers commanding views and a sense of seclusion. The short walk to the castle through woodland and along the coast makes for a scenic adventure.

7. St Mawes Castle

On the opposite side of the estuary from Pendennis, St Mawes Castle is one of the best-preserved examples of a Tudor artillery fortress. With its cloverleaf shape and ornamental stonework, it reflects the opulence of Henry VIII’s reign. Explore its bastions, enjoy the sea views, and imagine the cannons firing across the water.

8. Bude Castle

Unlike Cornwall’s older stone ruins, Bude Castle is a Victorian mansion with an interesting twist—it was built using early concrete. Founded by inventor Sir Goldsworthy Gurney, it now houses a heritage centre and art gallery. Its location on the Bude coast makes it a relaxing yet informative stop.

9. Caerhays Castle

Caerhays Castle is a picturesque, privately-owned estate near St Austell. Designed by renowned architect John Nash in the early 19th century, it’s surrounded by gardens that are internationally famous for their magnolias. While the castle is only open to the public at certain times of the year, it’s a must-see for those interested in romantic architecture and botany.

10. Carn Brea Castle

Perched on a hill between Redruth and Camborne, Carn Brea Castle resembles something out of a fairytale. Originally built as a hunting lodge in the 18th century, its turrets and panoramic views make it a unique destination. It’s now a restaurant, offering diners a chance to experience castle life with a modern twist.

11. Doyden Castle

A hidden seaside gem, Doyden Castle is a small cliff-top folly near Port Quin. Built in the 19th century as a retreat for a wealthy businessman, its romantic setting has made it a favourite filming location. Today, it’s a holiday let, offering a truly unique place to stay along the Cornish coast.
