The church of San Geminiano stands in the homonymous square in which the emperor Frederick II had his adviser Pier delle Vigne blinded, unjustly accused of treason. The building is linked to the primitive nucleus of Pontremoli and was born at the dawn of the Thousand as a chapel by the will of the Adalberti family. It is mentioned for the first time in a document dated 1095, which shows that Ildeberto del fu Ildeberto and Corrado Giudice del fu Azzone ceded their respective rights to the Chapel of San Geminiano to the Mensa dei Canonici di Santa Maria in Luni. It was the seat of one of the city’s six parishes until 18 December 1721, when the parish title was transferred to the Church of Santa Maria Assunta, elevated to Insigne Collegiata, the future Cathedral of the Diocese of Pontremoli. The patron saint’s day continued to be celebrated in the church until 1910, when Monsignor Angelo Fiorini, bishop of the city, transferred it to the cathedral. Even today the Church is the seat of the Confraternity of the Blessed Sacrament.

The exterior of the church is simple and has pilasters and pilasters that mark the facade with a play of shadows; above the tympanum it is possible to recognize the statue of San Geminiano. The church was demolished and rebuilt between 1670 and 1688; the interior of rare elegance consists of a single hall, richly decorated and frescoed, in part by Antonio Contestabili. Of particular interest are the medieval sandstone tondo depicting the Blessing Christ and the seventeenth-century wooden statue of “Christ going to Calvary” by Giovanni Battista Setti, known as the Roman from Piacenza.
