Strategic Coastal Defence in the Napoleonic Era

The Hackness Martello Tower and Battery were constructed between 1813 and 1814 amid the Napoleonic Wars, a period marked by threats from French and American warships targeting British and Scandinavian merchant shipping. Positioned on South Walls island overlooking Longhope Sound, the battery and tower formed part of a defensive network guarding this crucial anchorage. The battery was equipped initially with eight 24-pounder cannons arranged in a V-formation to cover the bay’s entrance, and the adjacent Martello tower housed a 24-pounder gun on its roof. These fortifications were designed to protect convoys waiting for Royal Navy escorts on their journey to Baltic ports.

Architecture and Military Life at Hackness

The Martello tower is an oval, three-storey structure with walls over 4.25 meters thick on the seaward side. Its ground floor contained the powder magazine, stores, and a water cistern, while the first floor served as living quarters for 14 soldiers and a non-commissioned officer, accessed by a removable wooden ladder. The roof held the gun emplacement, with iron tracks still visible that allowed the gun to rotate. The battery included soldiers’ barracks, a powder magazine, and a sloping parapet to aid cannon aiming. In 1866, the battery and tower were upgraded with larger 68-pounder guns and improved barracks, reflecting ongoing military concerns, though no combat action ever occurred.

Historical Significance and Later Use

Despite never engaging enemy forces, the Hackness defences represent a rare surviving example of Martello towers in Scotland—one of only three in the country, alongside Crockness and Leith. The site was briefly used by the Royal Navy during World War I but was not armed for direct combat. After military use ceased, the battery was converted to farmland, and the tower and barracks fell into disrepair until Historic Environment Scotland acquired and restored them in the 1990s. Today, the site preserves original features such as the gun emplacement, barracks furnishings, and military memorabilia, offering insight into coastal defence strategies and soldier life across two centuries.

Visitor Experience and Surroundings

Visitors to Hackness Martello Tower and Battery can explore the restored tower’s interior, including the barracks, magazine, and gun platform, and wander the battery’s open-air emplacements and parapets. The site provides commanding views over Scapa Flow, Orkney’s famous naval anchorage during both world wars, and the surrounding rugged coastline. The peaceful setting belies the site’s martial origins, inviting reflection on the strategic importance of Orkney in British naval history and the technological evolution of coastal defences.

Architectural Legacy and Military Innovation

Martello towers were inspired by a Corsican design that successfully repelled a British naval attack in 1794, prompting Britain to build over 100 such towers along vulnerable coasts. Hackness and Crockness are unique as Scotland’s only Martello towers, embodying this architectural and military innovation. Their thick masonry walls, compact design, and strategic gun placements exemplify early 19th-century defensive engineering. The Hackness tower’s restoration includes a 64-pounder Armstrong gun, illustrating artillery developments beyond the Napoleonic era.

Preservation and Cultural Heritage

Managed by Historic Environment Scotland, Hackness Martello Tower and Battery are protected as scheduled monuments, reflecting their national historic importance. The site’s careful preservation allows visitors to engage with Orkney’s maritime and military heritage, connecting local history with wider European conflicts. The battery and tower stand as enduring symbols of vigilance and preparedness, commemorating a time when the British Isles faced threats from across the seas but were ultimately spared direct attack at this location.
