Cavehill, historically known as Ben Madigan, is a basaltic hill overlooking the city of Belfast in Northern Ireland. It forms part of the south-eastern border of the Antrim Plateau. It is distinguished by its famous 'Napoleon's Nose', a basaltic outcrop which resembles the profile of the famous emperor Napoleon and is said to have inspired the famous novel Gulliver's Travels. Cavehill is also the name of an electoral ward in Belfast. All of Belfast can be seen from its peak, as can the Isle of Man and Scotland on clear days. Like Arthur's Seat in Edinburgh, it lies just a few miles from the centre of a major city. The towering cliffs can be dangerous, with many people needing rescue after seeking a shortcut to the summit or the higher caves.
