After a long weekend in Porto my memory card is full of photos of porcelain Azulejo tiles. I didn’t have to go out of my way to spot beautiful colours and patterns. I kept walking from one side of the street to another snap a photo. Tiles are used everywhere: on public buildings (the most famous at Sao Bento Railway Station), churches (exterior walls), restaurants, floors, street signs, beach walls, and residential properties. Azulejos tiles date back to 13th century (they were introduced to Portugal by Moors). The word ‘Azulejos’ comes from the Arabic word for ‘polished stone’. The patterns of Azulejos tiles are dominated by intricate geometric or floral design, plenty of blue and white, yellow and green colours. They are beautiful.
