Among these are the Churchill Barriers nearby straddling the ocean to link a number of Orkneys southernmost islands to its mainl&. Constructed to protect Britains naval fleet in Scapa Flow during World War Two its builders included a group of Italian soldiers imprisoned in this bleak & windswept part of Scotl&. In the course of this they not only played a part in changing Orkneys way-of-life forever but also transformed a simple Nissen Hut constructing through their labours a place-of-worship that still stands till this day a remarkable symbol of their identity & faith. & On This Rock tells the story of the strength & tenacity laughter & tears of the men who built the Italian Chapel showing how spirits defeated & despondent during years of exile were lifted by its creation. It does this with its own artistry & grace using folk-tale & myth to provide a fitting counterpart to the wonder & beauty of the building that inspired it.
