Azulejos are bluish tiles that are found all over Portugal, especially in Lisbon. In this colourful city it’s actually more unusual to find a wall without decorative tiles than with. Patterns and colours vary, and they date back to the 15^th century. There is in fact the National Azulejo Museum in Lisbon. I adore the artistic feel the tiles give to the city. To find some azulejos to take home, head to the Feira da Ladra  on Tuesdays and Saturdays in Campo de Santa Clara, in the Alfama district of Lisbon, which sells authentic tiles that have technically been ‘stolen’ over the years, as the name suggests (Feira da Ladra translates as ‘market of thieves’). The tiles you’ll find in tourist shops are best avoided as they are fake and generally of poor quality.
