5. Caerhays Castle and Gardens

This lavish castle and its gardens are exceptionally beautiful. This impressive building was built as a private residence and is not a royal castle with ancient history. Dating back to the early middle ages the home was owned by the noble Arundell family.

It was later inherited by the Trevanion family who commissioned famous architect John Nash to add to the castellated mansion. The debt incurred by the Trevanion family caused them to flee to Paris and the castle was bought by a local member of Parliament, Micheal Williams.

7. Chun Castle

Chun Castle is a large iron age fort near Penzance, thought to date back 2500 years. The circular fortress has two walls a few metres high and encloses the ruins of several roundhouses.

The history of the castle is largely ambiguous. But its elevated positioning with views over the Atlantic, Mount’s Bay and the land route to Penwith Peninsula suggest that this castle was used for defensive purposes.

Excavations of the area in the 1920s and 1930s brought about the discovery of a large amount of pottery. Historians suggest that this points out that the main phase of occupation was between the 3rd Century BC and the 1st Century AD.

Exploring these ruins will be an interesting contrast to the other grand and dramatic castles that are found in Cornwall. You’re sure to enjoy the unique history and experience.

St Mawes Castle is a well-preserved coastal fortress that was built between 1539 and 1545 by Henry VIII. It was built as part of a chain of forts to counter any attacks.

In addition to being extremely functional from a military point of view, the castle also boasts creative architecture. The clover-leaf shaped building shows off elaborately carved decorations of sea monsters and gargoyles.

9.Pendennis Castle

Also built by Henry VIII to defend the country from attack and invasion, Pendennis Castle has successfully defended Cornwall and played a significant role in both World Wars. This castle is in Falmouth, situated on the opposite headland to its twin, St Mawes Castle.

Both fortresses were built for the same reason but St Mawes has more elaborate architectural grandeur while Pendennis was more functional. The original building consisted of a simple round keep, enclosed with a curtain wall.

Over the years this was developed and expanded and improvements were going on until the end of World War II.

From the top of the keep, you’ll be able to experience what it felt like to scan the horizon for enemies (as well as have your breath taken away by the beautiful views of the sea and city).

10. Cromwell’s Castle

This 17th-century castle is on the beautiful Tresco which is one of the Scilly Isles. The Scilly Isles is one of my favourite places in the United Kingdom – it is completely idyllic. Cromwell’s Castle was built on a rocky point to guard the entrance to the safe area between the Scilly islands of Bryher and Tresco. The castle has a 50 foot high tower and 13 feet thick walls. It also has a rather spectacular location.

Today, Carn Brea Castle is a restaurant that has been run by the Sawalha family since the 1990s and it serves up Middle Eastern cuisine in the midst of Cornwall.
