Noirmont Point

Noirmont Point occupies the southernmost tip of Jersey, and the Martello tower here is one of the largest and most sophisticated of its type in the Channel Islands, significantly larger than the smaller coastal towers found elsewhere on Jersey and its neighbours. The tower was built to a standard Martello design but with modifications suited to the specific geography of the headland, and its granite walls are unusually thick and tall, rising to a gun platform that originally mounted artillery with clear sight lines over the surrounding sea and coastline.

The defensive ditch in front of the tower is cut directly into the granite of the headland, and a caponier at the ditch level allowed defenders to fire along the base of the walls, covering any attempt to approach the tower across the ditch floor. The tunnel system inside the headland is accessed through a heavy granite door at the base of the tower and extends a considerable distance into the rock, with passages connecting various chambers and magazines to the gun positions on the upper platform above.

The tunnel system at Noirmont Point is unusual for a Martello tower of this period, as most smaller coastal towers were simple defensive structures without elaborate underground works. The tunnels here were designed to allow the garrison to move between positions without exposure to enemy fire, and to provide secure storage for ammunition and supplies well below the level of the gun platform. The quality of the stonework in the tunnels is high, with regular arching and drainage channels cut into the rock floor, indicating a significant investment in the construction.

Noirmont Point was part of a much larger British defensive network that included similar fortifications across Jersey, Sark, Herm, Alderney and the Normandy and Breton coasts of France, and the Channel Islands were regarded as a key element in Britain's coastal defence strategy throughout the Revolutionary and Napoleonic period. The fortifications here were designed to deny the French access to a deep-water anchorage that could be used to support operations against the English coast, and the scale of the construction reflects the strategic importance assigned to the islands by the British military establishment.

After the end of the Napoleonic Wars the fortifications at Noirmont Point were largely abandoned and fell into disuse, though unlike many similar sites elsewhere they have survived in relatively good condition, with the granite construction proving durable and the site remaining in Crown ownership. The tunnel system and gun platform are still substantially intact, and it is possible to walk the ramparts and descend into the tunnels, experiencing something of the isolation and strategic vulnerability that defined life at these coastal outposts two centuries ago.

The headland itself is exposed and windswept, with the sea visible on three sides and the horizon constantly present as a reminder of Jersey's maritime position. On clear days the views extend to the French coast on the eastern horizon, and the strategic significance of the position for coastal observation and artillery control is immediately apparent. The walk to the tower from the nearest road involves a short but exposed section of coastal path, and the experience of approaching the fortifications on foot is not dissimilar to how a garrison would have received a supply party or relief force in the Napoleonic period.

The Noirmont Point fortifications are Grade I listed and form part of a Scheduled Ancient Monument, and the significance of the site is recognised as one of the most important Napoleonic-era coastal fortifications in the Channel Islands. The tunnel system is accessible on guided tours operated by Jersey Heritage, and the visit provides a vivid illustration of the military investment that the Channel Islands attracted during this period of heightened tension between Britain and France.

Noirmont Point has one of the largest and most sophisticated Martello towers in the Channel Islands, with an elaborate tunnel system cut into the granite headland.

The strategic significance of the position is immediately apparent from the panoramic views of the channel and the French coast visible on clear days.

The fortifications are Grade I listed and form a Scheduled Ancient Monument, and the tunnel system and gun platform survive substantially intact from the Napoleonic period.
