From a visit to a Franciscan Monastery within the walled city of Dubrovnik.  I was struck by the symmetry of the cloisters and when I took the image it was with the intention of converting it to monochrome as you see here.

I’ve done a little perspective correction in lightroom, boosted both the contrast and clarity.  Opened up the shadows a little, added a vignette and finished the image of with a slight split tone to give a hint of sepia to the image.
