Jersey is a Crown dependency. It has formal relationships with, but is not part of the European Union nor the United Kingdom. As might be expected, its setting between those two has shaped a great deal of its history. The medieval castle of Mont Orgueil overlooking Gorey Harbour is a mute testament to the shifting political tides that have washed the island, as are the elaborate works created during the German occupation between 1940 and 1945. Wineries such as La Mare take advantage of the pleasant climate, as does the 32-acre Durell Wildlife Park, founded by author and naturalist Gerald Durrell. His foundation now supports the facility, which is dedicated to preserving species at risk of extinction in the wild. Visitors are welcome to see and learn about the over 130 species they maintain, including a famous family of lowland gorillas. During your time on Jersey, you are also likely to spot an example of an indigenous domestic species: Jersey cattle, which are renowned for their high production of milk and cream.
