Overview
McArt’s Fort dominates the skyline of Belfast from the summit of Cave Hill, a basaltic outcrop that rises to 1,207 ft (368 m) above sea‑level. The ancient earth‑work sits on a flat stone platform measuring roughly 150 ft north‑south by 180 ft east‑west, protected on three sides by sheer cliffs and on the fourth by a man‑made ditch 10 ft deep and 25 ft wide. From the fort’s highest point you can survey the whole city, Belfast Lough and, when the air is clear, the distant coast of Scotland.
History
The site is an Iron‑Age rath, traditionally linked to the O’Neill dynasty that ruled much of Ulster. Local tradition connects the name “McArt” with Brian McArt, a member of the O’Neill sept who is said to have fallen in battle during the Elizabethan wars. 19th‑century antiquarian George Benn described the fort as a “bold and commanding” position, noting its strategic view over the approaches to Belfast.
In the 1800s the hill’s silhouette acquired the nickname “Napoleon’s Nose” because the profile resembles the French emperor’s profile. The same outline inspired Jonathan Swift’s reference to a “Sleeping Giant”, a phrase later echoed in Gulliver’s Travels.
A crude stone chair once stood on the summit, reputed to be the ancient throne of the O’Neill chieftains. It was vandalised in 1896, an incident recorded by Cathal O’Byrne. Folklore adds a Viking layer: treasure is said to have been hidden on the hill, and a silver armlet allegedly found on Cave Hill appeared in an 1856 Sotheby’s sale.
The five caves that give the hill its name provided refuge for the MacGilmore clan in the 18th century and, more famously, hosted the United Irishmen when they swore an oath of rebellion in June 1795.
What to See & Do
- The Fort Platform – Walk the flat stone surface and imagine the ancient warriors who once kept watch over the city. The surrounding ditch and cliff faces give a palpable sense of the defensive purpose of the site.
- Panoramic Views – From the summit you can see Belfast Harbour, the historic Belfast Castle below, and the rolling hills of County Down. On exceptionally clear days the Scottish coastline is visible across the North Channel.
- Napoleon’s Nose & The Sleeping Giant – The ridge’s profile is a favourite photo‑op for visitors; the silhouette is especially striking at sunrise or sunset.
- Cave Hill Loop – A 3.2 km (2 mi) circular walk that starts at the Belfast Zoo car‑park, climbs past the zoo, reaches McArt’s Fort, and continues to the highest point of Cave Hill. The route is rated “Easy”, takes 1–1.5 hours, and is family‑friendly. Pets are allowed on a leash.
- Nearby Attractions – The loop passes the Belfast Zoo, the 19th‑century Belfast Castle, the Devil’s Punchbowl (a semi‑circular depression once used for cattle corral), and several prehistoric cairns and a crannóg.
Flora & Fauna
Cave Hill’s limestone grassland bursts into colour in spring, when thyme, wild thyme and low‑lying heather carpet the plateau and attract a chorus of bees and butterflies. Summer brings a mix of bluebells and wild strawberries, while autumn paints the surrounding woodlands in amber and crimson. Red‑tailed hawks and kestrels are regular aerial visitors, and the occasional fox can be spotted along the lower paths.
Photography Tips
- Napoleon’s Nose – The profile is most dramatic at low light. Aim for the early morning (around sunrise) or late afternoon (golden hour) to capture the shadowed outline against the sky.
- City Panorama – From the fort’s highest point, use a wide‑angle lens to include the harbour, the River Lagan and the city centre. A polarising filter helps reduce glare on the water.
- Wildlife – Early mornings are best for birdwatching; a telephoto lens will let you capture hawks without disturbing them.
Nearby Attractions
- Belfast Hills – The wider range of peaks, including Divis and Black Mountain, offers further walking and cycling routes. See the dedicated guide at Belfast Hills.
- Belfast Zoo – Located at the trailhead, the zoo is a family favourite and provides rest facilities.
- Belfast Castle – A 19th‑century mansion set in landscaped gardens, reachable via the same loop.
- The Punchbowl – A natural amphitheatre formed by glacial erosion, offering a dramatic viewpoint.
