Details and patterns

Can you guess which European city these photo details were taken in. There's a small clue, some were taken in a graveyard overlooking the city. Last weekend my other half and I had one of our rare (once a year) weekends away just the two of us. Here is a collection of the architectural details and patterns that caught my eye. Not sure quite how I will use them but it's my equivalent of a sketch book, call it my photographic sketchbook.
