The name 'Cave Hill' appears to be a translation of the
Irish . The hill was originally known in Irish as (meaning "Madagán's peak"), after a king of
Ulaid (Ulster),
Matudán mac Muiredaig, who died in 856 AD. It could also be named after a later king,
Matudán mac Áeda (reigned 937–950). The later king's grandson, Eochaid mac Ardgail, was killed at the battle of Crew Hill in 1004, in which the men of Ulster were defeated by their old enemies, the
Cenél nEógain. It is from him that McArt's Fort derived its name. The residential neighbourhood at the foot of Cave Hill's entrance is derivatively known as Ben Madigan, with street names to match, and is a wealthy semi-outer city, semi-suburban area. The name 'Ben Madigan' can also be found attached to buildings and schools close to the area, e.g. the
Belfast Royal Academy has the Ben Madigan Preparatory School on the
Antrim Road.
United Irishmen Theobald Wolfe Tone and
Henry Joy McCracken allegedly met at Cave Hill in 1795 to take an oath to launch the
rebellion of 1798. McCracken was captured on Cave Hill in 1798. The crowning stone Giant's Chair of the O'Neill clan was apparently sited on Cave Hill summit until 1896 and gave its name to the nearby Throne Hospital. During
World War II, a bomb dropped prematurely during a German bombing raid on Belfast exploded, causing a large crater near the grounds of Belfast Castle. It is understood that
RAF Bomber Command was situated on Cave Hill in the early years of World War II before relocating to
Castle Archdale in
County Fermanagh. Hence the German bomb may have been intentional. On 1 June 1944, an American Air Force
B-17 bomber crashed into Cave Hill during heavy fog, killing all ten crew instantly. The incident inspired
Richard Attenborough's final film,
Closing the Ring (2007). Some scenes of the film were shot on Cave Hill. The site of the crash is accessed via Carr's Glen Country Park where the field, known locally as 'The Bomb hole Field' remains open to public. ==Geology==
