Southern France
From Tardis Wiki, the free Doctor Who reference
The Channel Islands were originally attached to mainland Europe via southern France in the distant past before they were broken away by the movement of tectonic plates over millions of years. Dragged by the forces of nature, they eventually settled in the English Channel. Britain and France disputed the ownership of the islands for centuries. The main islands were Jersey, Guernsey, Alderney and Sark, along with other smaller islands which were largely ignored and forgotten about by the average Briton or Frenchman, including the southernmost island, L'Ithe, where a Silurian shelter was located.
