Castle Cornet in Guernsey

Castle Cornet

The castle is built on a small island off the coast of Guernsey, to defend the busy trading harbour of St Peter Port. It has a strong natural position. The sea surrounds the castle and it is only accessible on foot at the lowest tides.

Before the enlargement of the harbour and the building of the Castle Emplacement, Guernsey Castle Cornet was nearly a mile off the shore of Guernsey.

The Castle has guarded the harbour for 800 years. You can explore the battlements and enjoy breathtaking views towards the other islands. Four Museums, four period gardens, the refectory and our shop are all here to discover.
