Every year since 1966 with affection and devotion, the contradaioli of the Terziere Casalino realize the imposing spectacle of the infiorata, with a floral carpet from Porta S. Agostino, continuing along Via Vannucci, ends at the foot of the cathedral.

It is from the devotion and affection of the contradaioli of the I° Terziere Casalino for their patron saint St. Luigi Gonzaga that the incomparable enchantment of the infiorata is created every year. This special day, one of the most important that the city offers to its visitors, traditionally marks the beginning of the events of the summer in Città della Pieve. Each edition is unique, original, and unrepeatable, changing the theme every year and always producing designs in original forms. Every year the flower arrangers work on the creation of a carpet of about 1000 square meters, laying flowers and essences of the Umbrian territory until the annual theme is complete.
