If asked where a famous island was dedicated to the Holy Archangel Michael, most people would probably answer the internationally famous UNESCO World Heritage Site "Mont Saint Michel" in France, located off the coast of the English Channel on the border between Normandy and Brittany. But a "St. Michael's Mount" can also be found in the southwest of England - beyond the European mainland, off the British Isles.

Godolphin House is a 15th Century manor house that is now owned by the National Trust. As well as the remarkably well preserved house there are vast grounds and local walks to explore. The house itself maybe more famous now for being used in the original 1970s BBC series Poldark. https://www.nationaltrust.org.uk/godolphin/features/godolphin-house

A visit to St Michael's Mount is well worth it, even if the entrance fee is a hefty £26.00 for the castle and gardens (2023). You have to make the necessary time for it. Avoid the weekends because then it is very busy!

Carn Brea Castle is an impressive structure, built into the rock on the top of Carn Brea. It is now a grade II listed restaurant, but was built in the 14th century as a chapel. Later, in the 18th century, the castle was altered into a hunting lodge. From high up here you can enjoy impressive views in every direction. In the 19th century, a beacon was lit here for ships to the north in the Atlantic Ocean. It has a lovely feeling of stepping back in time atop Carn Brea. To visit the restaurant check out the website. Booking is advised as it's a small, intimate dining space https://www.carnbreacastle.co.uk/

From here is a great view of St Michael's Mount, a tidal island that is home to a castle and a church. Access to the island is possible by foot across a causeway at low to mid tide. Looked after by the National Trust, you can visit St Michael's Mount, which is still home to a community of people, cut off from the mainland at every high tide. See their website for further details: https://www.nationaltrust.org.uk/st-michaels-mount The site is historically linked to Mont St Michael in Normandy, which is a very similar tidal island.

Originally built in the 14th century and turned into a hunting lodge in the 18th, Carn Brea is as astounding castle with a fantastic position. Just south west of Redruth, you can find it perched upon a hill with excellent views of the north Cornwall coastline and the surrounding landscapes. The grade II-listed castle is still a working building: a restaurant. You can book in for dinner but the castle is simple stunning to see from the outside.
