Narrow Lanes, Lucca
It's the main street in the old town. Its name means "ling wire" because it's very long and "thin" as a wire. It goes form the nearabouts of Piazza San Michele up to Piazza Santa Maria beside the Walls.
It has really a lot of shops af all kind: from jewels to underwear (I don't know why but there are many shops selling both of this goods in this street!!!).
Some shops are new and in contrast with the rest of Lucca (i.e. Footlocker...PUAH!!!!), some others are historical activities of Lucca (i.e. Caffe Di Simo, Carli Jewels or other jewelries).
When you are walking through Via Fillungo doing window shopping try also to notice what is over the shop's windows...some palaces are really gorgeous.
I know that it's impossible to visit Lucca without going through the narrow streets of the old town...if I put this activity in the "Must See" page it's because every lane deserves to be attentively observed.
For example walking under the arches in Via Elisa you could see the old man that fixes hand made straw chairs; or in Via della Rosa you could see a man, sitted in front of his vegetables shop, hulling beans looking at the walking people; or the old carts for goods parked near the Anphitheatre.
Another recommendation is to look always over your head... many towers, windows or balconies are hidden by the adjacent buildings and sometimes you can see them only if you are just under them and look upwards.
Great to wander around and enjoy the feeling of Lucca.
Not quite so good when your map has turned into papier mache and a hot shower is needed, found home eventually!
