A natural recess provides shelter
Like other nearby caves and crevasses, the large recess in which the Castle was built is the product of wind and water erosion over eons of time. Shelter from the elements and solar heat from the winter sun were probably good reasons for starting a home here. Other ideas have also been suggested, including protection, tradition, or perhaps the view! However, with no written records to guide us, maybe the real reasons will never be known.
