Les Landes, Archaeological site in north-west Jersey, Channel Islands.

Les Landes is a 160 ha coastal heathland in the parish of Saint Ouen, north-west Jersey, designated a Site of Special Interest in 1996. Heathers, gorse and bracken cover most of it, with ponds holding common toads. Two archaeological sites stand within it: La Cotte à la Chèvre, a small cave with Middle Paleolithic flints and a hand axe, and Le Pinacle, a natural rock stack by the cliffs.

La Cotte à la Chèvre, a small cave in the heathland, holds a Middle Paleolithic occupation layer where flints and a hand axe were found. Near Le Pinacle, a natural rock stack on the western cliff, artefacts from the Neolithic, Chalcolithic, Bronze Age and Iron Age came to light, together with the ruins of a Gallo-Roman temple. Grosnez Castle stands on the Grosnez headland above Rouge Nez.

The name Les Landes comes from the French for heathland, matching the heather and gorse that cover most of the 160 ha site. Finds at Le Pinacle span the Neolithic, Chalcolithic, Bronze Age and Iron Age, and include the ruins of a Gallo-Roman temple. Nearby stand the ruins of Grosnez Castle on the Grosnez headland above Rouge Nez.

Visiting is best done on foot, as the site has marked paths and coastal views to explore. Visitors should prepare for uneven ground and changing weather conditions.

The location is home to rare animal species, including western green lizards and specialized birds, that are seldom seen elsewhere. These fauna features make the site more than just an archaeological location.
