Le Pinacle, Archaeological site at Saint Ouen, Jersey, Channel Islands.

Le Pinacle is a rocky outcrop on the coastal edge of Les Landes in Saint Ouen that reveals layers of human occupation spanning thousands of years. The site displays tool-working remains, dwelling evidence, and the foundations of a rectangular temple built during the Roman period.

The site was first occupied by stone tool makers in prehistoric times and later used by communities throughout the Bronze and Iron Ages. The Roman construction of a temple there shows the location held importance across many centuries for successive populations.

The name comes from "pinacle", an architectural term for a slender topmost point, applied here to the rock needle above the sea. The surrounding Les Landes is a scientific site noted for its flora and fauna, and the pinnacle is a landmark visible from St Ouen's Bay.

Le Pinacle stands at the coastal edge of Les Landes in the north-west of Jersey, in Saint Ouen. The site is reached on foot through the Les Landes area, a site of special scientific interest for its flora and fauna. The rock is a natural formation visible from St Ouen's Bay, so it can be located from the beach before walking up.

The dolerite of Le Pinacle was quarried in the Neolithic and Bronze Age to make axe heads, so the rock itself was a source of tools. The pinnacle is a natural formation, not a built monument, and it can be seen from St Ouen's Bay.
