The first information on the Confraternity of San Giovanni Decollato dates back to the apostolic visit carried out by the nuncio Girolamo Scarampi in 1583, where the presence of this brotherhood is reported in the crypt of the Church of San Dalmazzo. In 1680, the rector of the confraternity announced his intention to build his own oratory, closer to the place of execution of the condemned prisoners he witnessed. On 19 May of the same year, the Bishop of Mondovì approved the necessary license for the construction. The construction was of limited dimensions, in fact an expansion was necessary around 1730, while the construction of the bell tower took place in 1750-51.
The church of the Confraternita di San Giovanni Decollato, also known as the Misericordia, overlooks via Roma with a Neoclassical façade juxtaposed with a mighty bell tower. The inside of the chapel is structured on two floors that divide the small room from the presbytery. At the centre of the presbytery, a beautiful Baroque altar stands out in which the nineteenth-century statue of Our Lady of Sorrows emerges, located within a niche, and the canvas depicting the Beheading of St. John, dated towards 1580 and attributed on a stylistic basis to Giovanni Angelo Dolce, a painter from Savigliano, active in the province between the end of the seventeenth and the beginning of the following century, who, with his language full of learned quotations, was able to be appreciated at the court of Carlo Emanuele I and in the circle of his noble collaborators , in particular the Tapparellis and the Saluzzos of Verzuolo and Manta.
