Where is Jersey?

At a distance of only 14 miles (22km) to the East, the coast of Normandy, France is closer to Jersey than mainland Britain, which is 100 miles (160km) away to the North of the island.  The close proximity to its neighbour has meant ties with France going back a thousand-odd years.  Until the Battle of Hastings in 1066, the Channel Islands formed part of the Duchy of Normandy.  Once King Harold met his gruesome end at the hands of the Norman army, and William the Conqueror became monarch of England, the islands became part of the Anglo-Norman realm.  It stayed that way until 1204, when King John lost Normandy to France.  As the Channel Islanders chose to remain loyal to the English crown, he granted them self-governing privileges, amounting to a certain financial and political independence.

What Languages are Used in Jersey?

Jersey once had its own language called Jérrais!  Spoken not so long ago (along with French and English), which descended from ancient Jersey-Norman.  During the German occupation in World War II the language proved a canny means of secret communication and outwitting the enemy.  Only a few of the older islanders still speak Jérrais today, although there has been a move to reintroduce language lessons in schools.  Given the historical tug of war between England and France over Jersey, it’s not surprising that islanders spoke French, as well as English.  Surprisingly, French remained the official language until the 1960’s.

Archaeology Findings

Archaeologists on Jersey have discovered 13 teeth from cave dwellers dating from around 48,000 years ago, and their characteristics suggest interbreeding with modern humans.  Teeth from two humans were unearthed between 1910 and 1911 at the archaeological site of La Cotte de St Brelade, at Ouaisné Bay, but scientists’ recent reassessment concluded they showed physical traits of both Neanderthals and modern man.

Famous Connections

Jersey was the home in exile of French playwright and author Victor Hugo, writers Anthony Trollope, and George Eliot. Also Gerald Durrell, known as a naturalist and ardent conservationist, who set up the Jersey Zoo (becoming the Durrell Wildlife Conservation Trust).

What is the Black Dog of Bouley Bay?

Jersey folklore tells of a huge black beast, with enormous eyes, which roamed the cliffs, dragging a chain behind it and terrifying the locals.  There were numerous apparent encounters with the Black Dog of Bouley Bay, and any account of these sightings had locals hightailing it home to bolt their doors.  One (more than likely) theory is that the stories were fabricated by smugglers.  If parishioners were frightened into staying at home, the smugglers could get on with the business of bringing their illicit booty on shore.
