St Michael’s Mount – our own special island

Most people in the UK won’t have heard of Marazion, but many will recognise the iconic shape of St Michael’s Mount, our very own fairytale island and castle. The mount is connected to the sandy beaches of Marazion by a winding causeway, covered for most of the day by the tides.

A fascinating history

Thousands of years ago, the island was a busy port, trading tin with Europe and is widely believed that the island was known to the ancient Greeks as Ictis. In 495, St Michael is said to have been seen by fishermen on top of the island and by the sixth century, it is thought that the island was a major religious centre.

An abbey was built on top of the island and granted to the Benedictine monks from Mont St Michel in France. Through the Middle Ages, the island was a major destination for pilgrims. Subsequently, it has seen several battles for its ownership. In 1588, the first beacon was lit on St Michael’s Mount to warn of the arrival of the Spanish Armada – seven years later, the Spanish returned and burned most of Penzance, Newlyn, Mousehole and Paul. Marazion and the Mount escaped unscathed from the invasion.

In 1659, St Michael’s Mount was purchased by Colonel John St Aubyn (he had been the last military governor of the island’s garrison) and it became the private home of the St Aubyn family who still live there today. In 1954, the Mount was gifted to the National Trust by the St Aubyn family, and is now managed by both the National Trust and the St Aubyn family, who work together in a unique partnership that supports the Mount’s vibrant island community, continuing a remarkable legacy of life and activity which has existed since prehistoric times.

Since 1954, the National Trust is responsible for the Mount’s conservation and upkeep, and the St Aubyn family run the Mount day to day and open it to the public, welcoming you to discover their extraordinary island home.

St Michael’s Mount today

Follow the footsteps of the pilgrims across the causeway or take a ferry boat to the island where you can discover a castle full of myths and legends, fabulous sub-tropical gardens and a real working island community.

The island is always open, subject to the tide of course.

The castle is often floodlit on Summer evenings, make sure you try and see it. The lights, especially reflected in a calm sea, make it appear as if it is floating in the air.

Opening times – 12 February to 27 October 2017

The castle is open every day (except Saturday) until the 27th October.

When the tide is open, it is a short walk from the mainland to the island across the historic cobbled causeway.
