1. St. Mawes Castle
St. Mawes Castle was built in the late 1530s as one of Henry VIII’s chain of coastal artillery fortresses. The fortress is not only incredibly well-preserved; it is also the most decorated compared to the rest of the artillery chain. The castle dons an elegant, clover shape. You get a spectacular view of the Fal Estuary below while standing atop the picturesque coast.
Wander through the beautifully landscaped castle grounds and gardens and keep a lookout for the sophisticated, historic carvings of King Henry VIII and his son Edward. After passing through the entrance bridge from the original guard tower, you’ll find yourself on the second floor of the gun tower. If you make a right, you’ll see the “oubliette” below the glass flooring, which is a dark hole where prisoners were kept underground.
St. Mawes castle has much more to offer regardless of the reason for your visit. Whether you are the history buff who enjoys “the perfect” architecture from Henry VIII’s reign, or you want to take a dip into history while strolling along with the stunning gardens, St. Mawes castle is a great place to start your visit to the top 6 castles in Cornwall.

2. St Catherine's Castle
Second on our list of the top 6 castles to visit in Cornwall is another one of Henry VIII’s artillery forts, St. Catherine’s castle. The castle was constructed in the 1540s and was kept in repair throughout the Tudor period. It was manned during the English Civil War before being deemed “ruinous” in 1684. Eventually, it was refurbished as a fortification for the Crimean War and the Second World War as a gun battery before returning to its former glory.
As one of Thomas Treffry’s finest works, St. Catherine’s Castle features a spectacular, elevated view of the Fowey estuary. However, perhaps the most impressive thing about the castle is the tower. There are two rows of gunports within the tower alongside the many narrow windows for small arms.
St. Catherine’s Castle is a wonderful site to visit. Situated less than a mile from Ready Money Beach and past a scenic climb through the woodlands, this artillery fort is a breathtaking stop that both tourists and locals alike love to visit.

Launceston Castle sits atop a grand, natural hill and outshines the landscape surrounding it. It has an unusual history and a 13-century round tower built by Richard, Earl of Cornwall, soon after the Norman Conquest.
Unfortunately, to reach the top, you must hike up the internal staircase. But, once you do, you will be rewarded with glorious sights of the historic town and countryside. Bring your camera up to snap some of the best pictures you can get in the world.
The castle does not only consist of physical beauty, but its history is just as rich. With over 1000 years of history found from excavation sites sprinkled around the tower, you will find yourself exploring a whole different era and learning facts you never knew.

4.Tintagel Castle
Tintagel Castle is a little more unique than the rest as it is one of the oldest. The island on which the castle stood was occupied by the Romans between the 3rd and 4th centuries and grew to be a busy trade site until 650AD. It was believed that King Arthur was conceived and birthed on Tintagel island, hence in 1650, the name “King Arthur’s Castle” stuck with the landmark.
The first notable attraction at the castle site is a 70-meter-long bridge spanning the mainland and the island. The mainland comprises a courtyard that leads into the castle and the mediaeval castle itself. The island is where the great hall stood, built on a sheltered, man-made terrace.
