The Best Castles in Cornwall

Cornwall’s coastline is nearly 700 kilometres long and so it’s little wonder that this often rugged and wild county had to have fortifications to protect against foreign invaders.   Cornwall’s oldest castles go back centuries – there are prehistoric forts and castles built into the cliffs that are unique to Cornwall.    The castles of Cornwall are set in glorious countryside.  Cornish castles protect entrances to harbours, towns, and the coastline.  They are strongholds and often practical rather than pretty.   Most of Cornwall’s castles are in ruin, but all of them have incredible stories, many have myths and legends associated with them, but all of the castles of Cornwall that we include in this article are worthy of a visit.   So come on in and discover the best Castles in Cornwall.

Tintagel Castle Cornwall

Tintagel Castle is Cornwall’s most famous castle and for me it’s my favourite of the best castles to visit in Cornwall. The ruins of Tintagel Castle are believed to be the fortress of the King Arthur of myth and legend.  King Arthur was the medieval figure, head of Camelot and the Knights of the Round Table.    The castle at Tintagel is half-built on a headland that projects into the sea and the mainland.  The castle is reached by a bridge, which provides stunning views over the surrounding coastline.  It is very easy to imagine and believe in many if not all the legends and myths of Tintagel. The cheapest way to visit Tintagel Castle is to join English Heritage.

Tintagel Castle in Cornwall

A brief history of Tintagel Castle, Cornwall

It’s hard to separate myth and historical fact at Tintagel.  Tintagel was at its strongest between the 5th and 7th centuries and was likely where the rulers of Cornwall held their residence – finds of luxury pottery imported from Mediterranean countries from that period have been found.   Tintagel inspired Geoffrey of Monmouth, a 12th-century writer, who named the castle in his work, the History of the Kings of Britain as the location where King Arthur was conceived.    The legend of Tristan and Iseult, a romance told since the 12th century, is also linked to Tintagel.   This chivalric romance tells of Tristan, a Cornish knight, and Iseult, an Irish princess, who Tristan was sent to escort from Ireland to marry his uncle, King Mark of Cornwall.  The couple fell in love on the journey.  The story has been retold over the centuries, as well as an opera adaptation by Wagner.

It appears to have been these legends that inspired Richard, the Earl of Cornwall, to build a castle at Tintagel in the 1230s.  The Duchy of Cornwall was created in 1337, at which time, the Great Hall at the Castle was in decay it was at this time that the first Duke of Cornwall, Edward, the Black Prince, reworked the hall into smaller buildings and it was during the 14th century that it was used as a prison.    It was in 1480 that William of Worcester, the writer, detailed Tintagel as the place of conception and birth of King Arthur, and by 1650 the name “King Arthur’s Castle” is first found.  It seems that by this time Tintagel and the legend of King Arthur were inextricably linked. It’s partly this history, myth and legend that make Tintagel for me the best castle in Cornwall to visit.

Tintagel Castle is owned by the Duchy of Cornwall, Charles, the Prince of Wales, but it is managed by English Heritage. The view of Tintagel Castle is one of our best views in Cornwall, come on over and see the others here.

Launceston Castle in Cornwall

A brief history of Launceston Castle, Cornwall

The first castle here was likely built not long after 1066 and would have been of earth and wooden construction.  It was rebuilt by Richard, the Earl of Cornwall, Launceston Castle was the administrative HQ for the Earl and has great views over the town and countryside. The best views are from the battlements, which you can reach by the narrow, dark internal staircase.  When Richard’s son, Edmund moved the Cornish capital to Lostwithiel in the 14th century Launceston Castle became a prison, her most famous being George Fox, the Quaker founder who was incarcerated here in 1656.

Captured by rebels in the 1549 “Prayer Book rebellion” (a popular revolt in Devon and Cornwall – more here) and was also occupied by Royalists during the 17th century English Civil War.  At the end of the Civil War, the castle was mostly stripped for building materials and a small jail was built in the centre.  Executions were also held here.  While the jail was the Cornwall County Jail, it was infamous for poor conditions and treatment of prisoners (just read the Poldak series book, Demelza for a little more on this!).  The jail closed in 1842 and the castle was closed and landscaped by the Duke of Northumberland.  During WWII US Army soldiers were hosted here and it was also used as offices by the Air Ministry, which left in 1956.

St Michael’s Mount, Cornwall

St Michael’s Mount is a tidal island in Mount’s Bay, Cornwall, linked to the nearby town of Marazion by a man-made causeway.   The island takes its name, according to Cornish legend St Michael appeared to a group of Cornish fishermen in AD495 – referenced in “the Great Vision of the Guarded Mount” in Milton’s Lycidas.  St Michael’s Mount is drenched in further myth and legend – from Jack the giant killer, to Tristan and Isolde.  It is a stunning sight from afar, a family home, and a fabulous place to get glorious views of the Cornish coast.

St Michaels Mount Castle in Cornwall

A brief history of St Michael’s Mount, Cornwall

The island of St Michael’s Mount was an important trading post from the first century AD – used as a port for trading Cornish tin.    It was in 1044 that a chapel was founded here by Edward the Confessor in a grant to the Benedictine Abbey of Brittany’s Mont Saint Michel.   After the Norman conquest of England in 1066, William the Conqueror granted much of England’s west to Robert, the Count of Mortain, and also gave him the title of Earl of Cornwall.  The Earl of Cornwall then granted St Michael’s Mount to the French Norman Abbey of Mont Saint Michel.  Following this, a priory was established on St Michael’s Mount by Bernard Le Bec in 1135.

In the 12th century, while King Richard the Lionheart was in the Holy Land during the Crusades, supporters of his brother John seized and held the Mount.   The Mount was used during the Civil War – held by Royalist supporters but the holders were forced to yield to the Parliamentarians.   Bought by Sir John St Aubyn in 1660 and was used as a summer residence by his family.  During the 18th century, the family built a new wing and St Michael’s Mount became a permanent residence.  The mount remained in the family until 1964 when the property was given to the National Trust, with a 999-year lease granted to the family to inhabit the castle and to manage the public viewing of historic rooms at the Mount.

Cornwalls best castles pendennis castle

A brief history of Pendennis Castle, Cornwall

Pendennis Castle was built between 1539 and 1545 when England was threatened by an invasion by the united forces of Catholic Europe. This was countered by Henry VIII, who established a national military and naval preparations program, which included the construction of additional coastal artillery forts. These were equipped with weapons designed to attack enemy warships and troop transports trying to seize control of British ports.

The deep estuary of Carrick Roads, located at the mouth of the Fal River, provided the ideal location for an invading force to establish a base. In order to defend it, Henry constructed gun forts at Pendennis and St Mawes, which were located on opposite sites of the river. It was also possible to defend the castle in any direction because of its circular structure, and many different gun positions were included.

A whole garrison or guard of up to 100 men was stationed at the fort only when there was an impending danger, such as the planned Spanish invasions of 1574 and 1579 (the ‘Great Armada,’ and 1596–1597). It had been anticipated that a Spanish fleet would arrive in Port Pendennis and seize control of Carrick Roads. However, even though this never occurred, the danger pushed the then Queen, Elizabeth I, to reevaluate her fortifications.

What to see at Pendennis Castle, Cornwall

It’s worth starting your visit by going around the perimeter to take in the stunning views of the Carrick Roads and the Fal Estuary, which are visible from the Castle, then taking in the exhibits illustrating the Castle’s history from Henry VIII to World War II.  The exhibits follow a series of themes.

  • Weapons of War– Check out the enormous guns in the Field Train Shed and learn about their incredible power for the age.
  • The Tudor Keep– Climb the spiral staircase to the roof for 360° panoramic views of the sea and see the full power of the Castle’s strategic location.
  • The Coast and Falmouth – Pendennis Castle has stunning views of Falmouth, the surrounding beaches, and the sea.  Spot maritime vessels of all types and fauna, birds, and sea life.
  • Guns and Cannons– Cannons and guns from the 1400s to WWII will be on display to help tell the exciting story of weaponry evolution and recreate the explosive atmosphere of past battlegrounds.

St Mawes Castle, Cornwall

St Mawes Castle is another of Henry VIII’s coastal artillery fortifications and it is the most ornately ornamented. St Mawes was one of a series of forts built between 1539 and 1545 to defend the vital harbour of Carrick Roads near Pendennis Castle from an invasion threat from Catholic France and Spain.  The area around Falmouth was deemed as somewhere that an invading enemy could gain a key stronghold and so heavy defence was necessary. St Mawes Castle has a lovely clover-leaf shape, which was once enclosed by eight octagonal walls, and you’ll find Latin inscriptions honouring King Henry VIII and his son Edward VI here. You can visit St Mawes Castle for free as a member of English Heritage.

St Mawes Castle Cornwalls best castles

A brief history of St Mawes Castle, Cornwall

Even though it is not precisely across the harbour from Pendennis Castle, St Mawes was built in 1540 as part of what was at the time Britain’s most complete coastal defensive project since the time of the Romans. Above the rocky beach, it towers over the river, defending the river’s entrance.

Amid Henry VIII’s falling-out with Rome, England found itself in a position of political isolation. In 1538, Henry VIII fortified the coastlines of England’s south and east shores, anticipating an invasion by the French or the Spanish. The Fal estuary could have provided a key opportunity for the enemy to create a foothold in England and it was in 1537 that, John Arundell, a prominent Falmouth citizen, and petitioner petitioned the monarch to have “blockhouses constructed upon our haven.”

In 1539, Henry VIII started construction on St Mawes, one of 30 new fortifications meant to protect essential ports and anchorages along the coast. The structure was completed in 1545. The Spanish Armada sailed close by a half-century later, and the region remained vulnerable and protected until after World War II.

St Catherines Castle Cornwall

A brief history of St Catherine’s Castle, Cornwall

St Catherine’s Castle was built following Henry VIII’s break with the Catholic Church and England’s subsequent isolation from Catholic Europe.  Treffy, who supervised the building of the castle was also involved in Pendennis Castle and St Mawes Castle.   The castle is named after the headland on which it stands and the views from the castle are spectacular.

St Catherine’s Castle was maintained throughout the Tudor years and was manned during the English Civil War (1642-1646), but fell into disrepair by 1684.   When the Crimean War brought further fears of invasion a two-gun battery was added to the castle and a parapet wall was reinforced. 

St Catherine’s Castle was brought back into military service in 1940 when it became an observation post and gun battery.  The Crimean War era magazine was used to store ammunition and the 16th-century tower was used to control a minefield laid across the Fowey River estuary mouth.  Read more about the best things to do in Fowey here.

Restormel Castle Cornwall

A brief history of Restormel Castle, Cornwall

Dating from the 13th century, Restormel Castle has been ruined since the 16th century but remains a spectacular place to visit.  Restormel comes from the Cornish “ros tor moyl”, which means bare hilltop spur.   The castle is located on top of an earth mound, is surrounded by a deep dry ditch and has 360-degree views of the surrounding countryside.  Restormel Castle history is a little lost to time, it was likely begun by the Earl of Cornwall, Richard, alongside his other Cornish Castles, Launceston and Tintagel.  However, his son Edmund, who moved the capital of Cornwall to the nearby town of Lostwithiel likely completed the existing buildings.    King Edward III made his son, Edward – aka the Black Prince – the Duke of Cornwall and deeded him what we know today as the Duchy of Cornwall.  The “deed of Seisin” of 1337 detailing this land grant provides the most complete survey of the lands and Restormel Castle.  The castle received repairs through the Middle Ages but declined as waste from tin mines on Bodmin silted up the River Fowey. 

Restormel Castle is one of our favourite things to do near St Austell, you can check out some of the others here.

A small contingent of troops was sited here during the Civil War – Cornwall was firmly “for the King” and then from the end of the Civil War, it became a tourist attraction with trees and planting enhancing the ruins.  The ownership of Restormel Castle was transferred to the state in 1925 and has been managed by English Heritage since 1984.

Chun Castle, Cornwall

Chun Castle Cornwall is located on the peak of Chun Downs near Penzance, Cornwall, and the castle is an Iron Age hill fort with spectacular views of the surrounding countryside. Following archaeological digs of Chun Castle, the remnants of six circular homes and one oval house, erected later in the post-Roman era, have been discovered. There are two stone walls around the fort, each roughly three meters high, which are flanked on the outside by an exterior ditch.

Chun Castle Cornwall

A brief history of Chun Castle, Cornwall

A large amount of pottery was discovered during excavations in the 1920s and 1930s. Their findings suggested that the major era of occupancy took place between the third and first centuries BC, with a later occupation in the fifth and sixth centuries AD. With its prominent position and great views of the Atlantic, Mount’s Bay, and being the sole land passage to the Penwith peninsula, Chun Castle was almost certainly built for defensive purposes and may have even been used to defend the lucrative tin mines, like Geevor nearby.

In light of the fort’s closeness to the much earlier Chun Quoit, it is possible that it was erected on the foundations of even older construction. Chun Downs also has two more famous barrows, one to the northwest and one to the southwest of Chun Quoit, located on the same property. The discovery of a furnace on the fort’s northern fringes, which included tin and iron slag residues, suggests that the fort was used for mineral processing throughout the Iron Age. Locals relied on a well located inside the fort’s inner walls for water until the 1940s, and water continues to flow from the well to this day. For a variety of domestic and superstitious purposes, such as the promotion of perpetual youth, it has been used in many cultures. Chun Castle is still visited by pagans on religious holidays, just as it was hundreds of years ago.

Caerhays Castle, Cornwall

The privately-owned Caerhays Castle and Gardens is located midway between Truro and St Austell in a valley overlooking Porthluney Cove.  The family still live in the castle, and it’s possible to take a guided tour of the public rooms of the Castle, but it’s the gardens that are the main attraction here.  There are 140 acres of woodland gardens and Caerhays Castle is home to a National Magnolia Collection.  It was soon after the beginning of the twentieth century that the discoveries of plant hunters in China had an impact on the surrounding parks and forest gardens. The production of the first x williamsii camellias was one of several hybridization projects that have taken place at the Caerhays estate since then. These camellias were used to help build the woodland gardens that are now visible and enjoyed by visitors.

The gardens here were created about a castle built by John Nash in 1808.  Since 1370 only two families have lived here and it’s the current Williams family that created the gardens that you see today.  J.C.  Williams sponsored the plant hunters heading to China, as well as experimenting with daffodil breeding and hybridization.  Caerhays was also chosen as a place to test new varieties of rhododendrons coming over from China and the cluster in the quarry at the bottom of the hill at Caerhays is magnificent.

best castles in cornwall gardens at caerhays castle

A brief history of Caerhays Castle, Cornwall

John Nash erected a beautiful castle in 1808, which inspired the historic gardens. When the Williams family took over 150 years ago, it was a decaying castle surrounded by a deer park.

The casual forest garden is a horticultural hotspot. Williams was a major daffodil admirer, and much of his hybridization technique came from the time’s experimental tactics. Williams financed future plant-hunting excursions that inspired the bright blossoms found in the garden today. The national magnolia collection is one of the most important collections in the British Isles, with around 450 varieties.

Caerhays is renowned for its magnificent camellias, magnolias, and rhododendrons, but it is also a haven for all common Asiatic shrubs and is a gardener’s paradise.

What to see at Caerhays Castle, Cornwall?

The 140-acre garden at Caerhays is filled with spectacular spring blooms, such as magnificent tree magnolias and rhododendrons and rare woodland trees and shrubs that come mainly from China. Because of this, it has a lot to offer both people who love gardening and people who want to look at and enjoy the blooms. It’s one of the best places to be for people who love magnolias and rhizomes.

For nature enthusiasts, the rhododendrons near the slope’s base are must-see. The national magnolia collection estimates the numbers to be over 450 species and is one of the most significant collections of its type in the British Isles. Even the best gardeners think that Caerhays is a beautiful place to visit. It has a lot of common Asian shrubs, like camellias, magnolias, and rhododendrons.

Cromwell’s Castle – Tresco, Isles of Scilly

Located on a rocky peninsula overlooking the beautiful bay between Bryher and Tresco, the round tower of Cromwell’s Castle was constructed after the capture of the Royalist Scillies by the Cromwellian forces in 1651. It is one of the few remaining Cromwellian fortifications in the United Kingdom. This is the only castle in Cornwall on islands.

A brief history of Cromwell’s Castle, Cornwall

The defences were demolished during the building of the fort to create a place for King Charles’s Castle, which was built on higher ground in the 1550s but was subsequently discovered to be improperly sited. During the final castle’s construction, it was substantially demolished to provide construction stone for the new structure.

The Royalists maintained their position in the Scilly Isles during the whole Civil War. Relations between the Netherlands and the United States were becoming more strained, and so on the arrival of the Dutch troops off the coast of the islands in March 1651, the Royalist privateers were ordered to pay restitution. Robert Blake, who had been lauded as the most successful admiral of the 17th century, was instructed to retake these strategically important islands because of his presence in Parliament.

After Blake’s success, the construction of the Castle in 1651 was a fast reaction, and it served to secure one of the most important routes into the interior of the islands, in addition to the deep-water entry to the port of New Grimsby.

No ship could expect to land men on this side of the Tresco without first destroying or taking Tresco Castle, and even if they were successful, defeating Tresco Castle from the sea would be a long shot. Nearly a century later, a cannon platform was constructed on the seaward side of the fort.
