I have uploaded some posts on Narrow Alleys; namely, of Dubrovnik, Split, Szentendre etc.
I found narrow alleys fascinating.
You never know what they lead to; you never know what is at the end of the alleys.
The alleys in Annecy are fascinating, to say the least.
The medieval buildings on either side of the alleys are usually pastel colour and nicely matched.
Walking along the alleys is like walking back in time.
You just go deeper and deeper in history.
