At Plaça de la Boqueria, where four side streets meet just north of Liceu metro station, you can walk all over a colorful 1976 pavement mosaic, with one tile signed by the artist, the great Joan Miró. The mosaic's bold colors and vivid swirling forms are instantly recognizable to Miró fans, though plenty of visitors stroll right over it without realizing. Miró chose this site as it's near the house where he was born on the Passatge del Crèdit.
The mosaic was the epicenter of a terrorist attack in August 2017 and the 14 victims are commemorated here with a 12m-long engraved memorial inscribed with an anti-violence message in multiple languages.
