Rozel harbour lies on Jersey's north coast and looks straight out toward the 'Les Ecrehous' reef, some 8 miles offshore. Sheltered from most wind directions the harbour became a valuable refuge for small fishing boats during the late 18th and early 19th centuries

Rozel pier was re-built in 1829 to provide shelter for the growing number of small fishing boats involved in the oyster fishing trade who were unable to fit into the, by then, very busy Gorey Harbour as the industry developed.

Due to the harbour being tidal, the fishermen who operated from this harbour went on to build 'viviers' amongst the rocks just inside the harbour in order to keep their catches fresh for market. The remains of these brick structures are still very visible today
