Well I was stuck for the answer to that question. It was tempting to think that it was a shelter for a religious hermit, albeit tarted up a bit. Looking it up on the internet wasn't easy either because I didn't know what it was called (mind you, if I knew that, I wouldn't need to look it up!) Anyway dear reader, I persevered just for you and it is in fact an explosives store for a nearby quarry. As you can see it is empty but do not worry - the reason for that is that the quarry is no longer working!
