Montecalvario is the neighbourhood to the west of Via Toledo. It takes in much of the Spanish Quarter and the area to the north, all the way up to the National Archaeological museum.
Within Montecalvario, Via Pignasecca is the street just to the north of the Spanish Quarter. It’s home to the oldest street market in Naples but I never get to go as I’m usually working when it’s open (8am to 1pm). Here are some pictures from the web to give you an idea.
The market is best accessed along Via Pignasecca which leads from Piazza della Carita on Via Toledo. On the west side of the square, in the entrance to the building on the corner with Via Pignasecca, there’s a nice example of a hawk wing staircase.
I hope to fill up this post with more photos on my next trip, so I’ve put places to eat in Pignasecca in a separate post.
