North Stack, or Gogarth North Stack, can also refer to the headland opposite the island. This is the site of a redundant fog warning station, comprising a number of buildings, including the Trinity House Magazine, built-in 1861, where shells for the warning cannon were stored. These buildings now house a bird-watching observatory,[2] giving a view of South Stack lighthouse across Gogarth Bay,[2] and the studio of artist Philippa Jacobs.[3]

Rock climbingEdit

The Precambrian quartzite cliffs of this headland, including the North Stack Walls and Wen Zawn, provide one of the largest areas for rock climbs in Britain, and contain important traditional climbing routes such as A Dream of White Horses (HVS 4c, Ed Drummond and Dave Pearce, 1968), The Cad (E6 6a, Ron Fawcett, 1978), The Bells! The Bells! (E7 6b, John Redhead, 1980) and Conan the Librarian (E7 6b, Johnny Dawes, Craig Smith, 1986)[4][5][6]

Crash siteEdit

The stack was the site of a crash of a B-24 bomber of the US Eighth Air Force on 22 December 1944 that killed the eight crew on board.[7]
