The ruined chapel on the summit of the Rock's centre crag was dedicated to St Michael in 1409, however according to geologists, Roche Rock has been in the lee of the mountainous clay waste heaps, and overlooking the plateau of northern coastal Cornwall, for over 270 million years, formed by a geological process every bit as fascinating as the results look today. They say that big movements underground in the late Carboniferous period caused boro-silicates in the local granite to 'boil'. This fluid separated from the other molten rock, then bubbled up towards the surface on its own, much like the globules in a lava lamp, and finally cooled to its present state. The unique look of the Rock � its texture, its shape, and its position in the locality � must have had a great impact on the first inhabitants of this area. Also seen in horror movie The Omen.
