This is the introduction page for a new series of articles on Jersey's changing coastline. At present it is very much a work-in-progress, drawing together some appropriate existing articles. But more new material is in the course of preparation and we will be adding many photographs new to the site, of coastal works, land reclamation and other projects, so keep visiting to see how this page and the associated articles develop.

ersey's coastline has changed significantly over the centuries. In the last 200 years land has been reclaimed along several stretches of coastline, for various reasons, including the creation of new harbours, the laying of railway tracks and, more recently, simply to create areas where rubble from demolished old buildings can be dumped while new ones are built in their place.

Pre-history

But much earlier in history it was changes in sea levels which had the most dramatic impact on the island's coastline.

The size of the island of Jersey varied dramatically in prehistoric times, and at some stages it was not an island at all, but a hilly area linked to the Cotentin Peninsular of Normandy by a flat plain. At other times the sea was much higher and very little of the island was exposed above sea level. Geologists differ in their opinions as to when these variations occurred, but although it has generally been accepted that the sea surrounded Jersey several thousand years ago, suggestions have been put forward more recently that this did not happen until much later, possibly little more than a millennium past.
