Castanyada and Halloween with Kids in Barcelona 2026, 1 of 24: Plaça del Pi



A small pedestrian square in front of the Gothic basilica of Santa Maria del Pi, shaded by a pine that has stood here for centuries. There are no swings, but the flat traffic-free paving lets toddlers run while parents sit at a café terrace, and most weekends an artisan food market fills the space. Pair it with the chocolate shops on nearby Carrer Petritxol.
