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.

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.
