Castles in Cornwall - Caerhays Castle

Last year’s ‘I’m a Celebrity… Get me out of here’ at Gwrych Castle in Wales fueled our desires to visit some of the most interesting castles in Cornwall, and now the national lockdown has started to ease, we thought this was the perfect opportunity to do just that!

With over 400 miles of coast, it should come as no surprise that there are many wonderful castles in Cornwall, some of which you can still see to this day. From relics to ancient ruins, there are many fascinating castles for you to explore which will take your breath away.

Read on to see a few of our personal favourite castles to explore across Cornwall…


Pendennis Castle, Falmouth

Overlooking the magnificent bay of Falmouth and the Fal estuary, Pendennis Castle is one of a handful of distinctive circular artillery forts which were built in the 1540s – during a period of national emergency. The Castle has some fascinating history, from the time of Henry VIII to the Second World War.

The area was critical in defending England, to prevent an enemy attempting to invade the country from the southern coastline.

Originally part of Henry VIII’s national defensive preparations around 1539 – 1547, Pendennis Castle, with its 360° view, has kept a lookout over the port of Falmouth for over 400 years. To the North East, you will notice St Mawes Castle perched overlooking the other side of the estuary.

During the First and Second World Wars, Pendennis Castle was at the heart of Falmouth’s defence against invasion and still stands proudly over the town today.

A great day out for all the family to enjoy learning about the history of the castle, and certainly one of the most famous landmarks in Cornwall. Pendennis Castle also features on our list of the top 6 things to do in Falmouth.

St Mawes Castle, St Mawes

Almost identical in shape to Pendennis Castle is the spectacular St Mawes Castle. Overlooking the Roseland Peninsula and situated on a headland, on the top of St Mawes, this iconic castle has a striking presence in a truly majestic position opposite its counterpart Pendennis Castle.

St Mawes Castle’s positioning opposite Pendennis Castle encouraged crossfire to take place across the bay, which was crucial when warding off invaders and attacking from two angles.

Still adorning the walls, visitors will be delighted to see marvelous historic carvings and text about Henry VIII.

Tintagel Castle, Tintagel

Of all the castles in Cornwall, this one is probably the most well-known. Find yourself immersed in the history and myths of Tintagel Castle, from the Knights of the Round Table to the legend of King Arthur, this dramatic fortress on the rugged north Cornwall coast is a must-see on our castle tour of Cornwall.

With a new slate footbridge in place, Tintagel Castle is more accessible than ever**. For the past 500 years, two halves of Tintagel Castle have been separated but now, thanks to the landmark project, they have been reunited, making visiting much easier. The bridge looks pretty spectacular in its own right too, with thousands of slate sheets placed vertically to create an iconic look.

From the 5th to the 7th century AD, Tintagel was a stronghold and home to some important rulers in Cornwall. Legend and History are intertwined in Tintagel.

Richard, Earl of Cornwall, built a castle here in the 1230s. As this site had no military value – many presume legend must have inspired him to build the castle here. After the castle had fallen into disrepair, these mythical associations with Tintagel kept the town’s appeal alive to this very day.

A Cornwall boat trip from Port Isaac can offer a unique viewpoint of this historic site, with the chance to spot some of the local marine life at the same time.

Launceston Castle, Launceston

At the top of the castle, you will be able to witness the stunning views across the countryside and the historic town of Launceston, via the internal staircase.
