Dun Briste or Dún Briste meaning Broken Fort in Irish refers to this small but impressive vertical island on the edge of the Atlantic.

Though only 501 metres (1,644 ft) high, its isolation from other hills, steep slopes and volcanic appearance makes it appear much taller than it is. Due to its height relative to the surrounding landscape the hill qualifies as a Marilyn.The Great Sugar Loaf is composed of Cambrian quartzite, in contrast to the rounded mountains to the west, which are made of Devonian granite. Popularly mistaken for a volcano, it is in fact an erosion-resistant metamorphosed sedimentary deposit from the deep…
