Mont Orgueil is a castle in Jersey. It is located overlooking the harbour of Gorey. It is also called Gorey Castle by English-speakers, and lé Vièr Châté (the Old Castle) by Jèrriais-speakers. The site had been fortified in the prehistoric period, but the construction of the castle was undertaken following the division of the Duchy of Normandy in 1204.
On 2 April 2006, after a long building programme the castle was reopened to the public by the Lieutenant-Governor of Jersey. Restoration work has opened up previously inaccessible areas of the castle to the public.
