Make merry like the locals do. You will find most shops remain closed as the extensive street festivities go on throughout the day. The cause for celebration is the city's patron Saint San Giovanni (St John), whose feast day is on June 24. Some specific highlights of the fun festivities include the regatta, which assembles near the Ponte Vecchio as well as the impressive fireworks display organized in Piazzale Michelangelo around 10p.
