In 1884, while the Barcelona City Council renewed its city vow to Sant Roc, which it had left to meet in 1851, the residents and merchants of the neighborhood choose the members of what would be the first officially established Feast Committee of Sant Roc and, therefore, of which many records and accounts are preserved. The new Feast Committee would give a big boost to the celebrations in its more festive and popular aspect.
New decorations are made by the neighbors, with pennants all across the square and with seven large banners for the seven streets in the neighborhood. They complement the ring games with the first "Cucanya" (greasy pole), which is brought from Sarrià. Music bands are hired to participate in the entourage of the saint and to perform enjoyable evening concerts and dances at night. The "putxinel·lis" representations are already a classic of the festivity. The tradition of "Panellets de Sant Roc" started -a sweet with a secret recipe and well known all over-, and, thanks to bishop Català, the sharing of sweets and bread for the poor. In 1894 a big feast is held for the Centennial of the Flag dels Bastaixos de la Plaça Nova.
In the last third of the nineteenth century the celebrations of Sant Roc de la Plaça Nova spread around the adjacent streets: de Ripoll, de la Palla, de la Tapineria, dels Sagristans... The Feast of the Plaça Nova, however, enjoyed a wide recognition throughout the city. Big crowds flocked to see the illuminations and to attend the dances "dels envelats" and "dels cafés", but, above all, the fireworks that ended the celebrations, which for decades were the most celebrated of the entire city of Barcelona.
