I’m not sure what this opening/doorway was about – it didn’t seem to go anywhere. It may very well have been a guard station.
For the most part, my inclination is to created black and white images from my digital photography of architectural details – it’s generally the subtle interplay of light and shadow that attracts me. But, this stonework was such a subtle tone I thought I’d produce it here in colour, too – though I will readily admit the soft tones may not come across as on my monitor, especially if our monitors don’t have a similar calibration. Nevertheless, I hope you can appreciate the delicacy of tone.
What surprised me, was the way my fellow tourists seem to simply walk past the doorway with hardly a second glance – didn’t the see it!
