A city where it is impossible not to look at what is beneath your feet is Lisbon, Portugal. The endless intricate patterns of the cream and black cobbles automatically draw your eyes down. Known as calçada (Portuguese Pavements) some, like the wave pattern above and below in Praca Dom Pedro IV Square (Rossio), can even interfere with your balance and make people look as though they are floating above the pavement.

In Belém coloured marble is used with the flat cobbles to create patterns and pictures including a map of the world depicting the voyages that Portuguese explorers made during the Age of Discovery.
