Portuguese pavement, known in Portuguese as calçada portuguesa or simply calçada (or pedra portuguesa in Brazil), is a traditional-style pavement used for many pedestrian areas in Portugal. It consists of small pieces of stone 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 colonies, especially in Brazil. Portuguese workers are also hired for their skill in creating these pavements in places such as Gibraltar. Being usually used in sidewalks, it is in town squares and atriums that this art finds its deepest expression.
One of the most distinctive uses of this paving technique is the image of Saint-Queen Elizabeth of Portugal (Santa Rainha Isabel), in Coimbra, designed with black and white stones of basalt and limestone.
