The waves of Copacabana

Portuguese pavement, known in Portuguese as calçada portuguesa or simply calçada is a traditional-style pavement used for many pedestrian areas in Portugal. It consists of small flat pieces of stones arranged in a pattern or image, like a mosaic. It can also be found in Olivença (a disputed territory administered by Spain) and throughout former Portuguese territories. Portuguese workers are also hired for their skill in creating these pavements in places such as Gibraltar and, specially Brasil.
