The picture above shows another example of Portuguese "Calçada".
The street above is in Libon´s downtown. In that part of Lisbon, most streets have stone handwork as seen in the picture but you can also find different patterns.
Artisans are called "Calceteiros" and, as happens with many crafts, they´re becoming rare. There´s still a few Portuguese companies working both for private clients and businesses but prices per m2 aren´t exactly cheap.
I think "Calçada" is really beautiful and stylish.
