In Siena it is possible to visit numerous churches where the memory and remains of great personalities of the religious community have been venerated for centuries. Indeed, it is precisely in the city of the Gothic that the right arm of St. John the Baptist, the same one that baptized Jesus, is found: the relic was donated to the city by Pope Pius II Piccolomini in the 14th century, and at the same time, the chapel that still preserves it was built. The arm is housed in the Siena Cathedral, surrounded by works of great artistic value bearing the signatures of Donatello and Pinturicchio.
In the Basilica of San Domenico, the remains of St. Catherine, patron saint of Italy and Europe, have found a safe place: the saint's head and finger are displayed here, always surrounded by devout visitors who pay their respects to her; her personal effects, on the other hand, are found at the sanctuary, the former home of Caterina Benincasa, later sanctified.
In addition to this, in Siena it is possible to go to the Basilica of St. Francis, where the Sacre Particole (Sacred Particles), miraculous hosts immune to the passage of time, are kept.
