Did you know that the walls of Lisbon are considered an open-air exhibition of urban art? Well, Portugal is in the top 10 of countries with the most remarkable street art. Wall art is a treasure of Lisbon which is not secret or hidden in back streets or suburban neighbourhoods but in plain sight. You will find strikingly colourful, whimsical, sometimes provocative murals a bit everywhere around central Lisbon, especially in the areas near the river such as LxFactory or Time Out Market. Some of them are iconic works of art by well known national and international artists such as Banksy, Vhils, Utopia or Shepard Fairey, not to mention Bordalo II and his wall installations made of recycled waste. So go and take that walk on the wild side!
