It is quite magnificent isn't it @stef1! I love old architecture like this because it carries so much history!

I wonder how skilful the stonemason were creating such complex and beautiful buildings.

So true! and yet, with all our modern machinery, knowledge, manpower and technology - they just don't make things like they used to. The focus just isn't on quality anymore - it just seems to be about the quickest, cheapest way to do things, which is sad really.
