At Plaça de la Boqueria, where four side streets meet just north of Liceu Metro station, you can walk all over a Miró – the colourful mosaic in the pavement, with one tile signed by the artist. Miró chose this site as it's near the house where he was born on the Passatge del Crèdit. The mosaic's bold colors and vivid swirling forms are instantly recognisable to Miró fans, though plenty of tourists stroll right over it without realising it. Near the bottom of the work, there's one tile signed by the artist.
