Portuguese pavement is the traditional paving used in most pedestrian areas in Portugal and old Portuguese colonies such as Brazil and Macau. Being usually used in sidewalks, it is in plazas and atriums this art finds its deepest expression.
One of the most distinctive uses of this paving technique is the image of the Saint Queen Elizabeth of Portugal, in Coimbra, designed with black and white stones of basalt and limestone.
Origins
Paving as a craft is believed to have originated in Mesopotamia, where rocky materials were used in the inside and outside of constructions, being later brought to Ancient Greece and Ancient Rome.
The Romans used to pave the vias connecting the empire using materials to be found in the surroundings. Some of the techniques introduced then are still applied on the Calçada, most noticeably the use of a foundation and a surfacing.
Arab presence in the Iberian Peninsula left traces in the art of paving. To provide much needed water to crops, the Moors engineered a complex system of dams and waterways. Examples of the latter, known as acequias, can still be found in Portugal and Spain.
Setting the stones
Upon a well compacted trench of argillaceous materials, craftsmen lay a bedding of gravel, which will accommodate the stones, acting as a cement.
