Rossio (Praca Dom Pedro IV) - in Lisbon, Portugal. The statue of Dom Pedro IV (first emperor of Brazil) stands proudly in the middle of the square. The National Theatre stands in the background. The wave patterned mosaic hand cut stone cubes give rise to the square's nickname - "Rolling Motion Square" and these type of designs have been repeated across Lisbon.
