In Portugal, the sidewalks are usually paved with a stone, limestone. In areas where granite is mined it is also used to cover the sidewalks.
Most of the population of any city daily walks on calsada (paved sidewalks, roads, and sometimes horizontal surfaces indoors). (1).
We are so accustomed to it that do not even notice the existence of this coverage.

Nevertheless, this is a form of ancient art, which always in front of us.
When we simply walks away from our daily route, we stop to enjoy the beauty of the grid interlocking stones, thoroughness of the image execution.

Only when "calçada" (pavement) is partially destroyed or damaged - we can not to miss it.
Nevertheless, the damage can be avoided. Calsada pavement can serve for a very long time if correctly installed. Natural stone is more durable building material - just look at the ancient buildings. Who was not surprised by durability of the ancient Roman roads covered by calsada?
How to explain the poor conditions of many roads and sidewalks in this country?

Obviously, lack of maintenance explains much, appropriate maintenance of the sidewalks coatings especially with large people traffic could help to avoid most of the problems.

Permanent digging out and repaving often due to inadequate planning gives one part of the answer.

However, the explanation would be incomplete without addressing the specific conditions of the work such as: lack of staff, lack of training grounds, the actual project time and cost associated with implementation of the work, etc.

"Calçada" should not be seen as impersonal cover, such as asphalt.

Let me give you an example: there is a big difference in the price and quality of work done by a tailor-craftsmen and the garment industry.

Similarly, the result of work performed by a master-calceteiro (2) is quite different with the work done by a non-professional team.

The question is also in what material is chosen to cover the sidewalks.

The purpose of this site is not only to provide information on the master-calceteiro Arthur, but more importantly, to make a contribution to conservation of this art.

All presented works have been done by Arthur, if otherwise is not explicitly stated.

1. Natural stone pavement of sidewalks, roads, and sometimes horizontal surfaces indoors is called "calçada", as the term is broader than just "pavement", which is normally used for the roads and where choice of stone, painting and laying method, method of processing, etc. usually do not change. Calsada it is also a pavement, but one of a courtyard, of tracks and sidewalks in gardens and parks, of the first floor of a stone building  - is not a usual pavement, but the calsada. We also can call it “mosaic pavements”.

2. For consistency of the presentation, I use the term "calceteiro", as the term is broader than "paver", according to the logic of the above (1). Example: calceteiro cuts the stone to desired shapes when doing his job, that is the fundamental  distinctions of laying of synthetic coatings with a definite, manufactured form of stone, tiles and plates.
