The Carmelites, who came to the island from Catalonia in 1509, arrived in Bosa in 1556 and settled at the convent adjoining the church of St. Anthony del Ponte, to carry out their work of evangelization on the one hand and assistance on the other. The place became unhealthy due to the numerous floods of the Temo River, was abandoned and in 1606 they moved to another site near the Church of St. Mary of Relief, near the Gate of St. John and at the same time began always in the vicinity, the construction of the new monastery. In the second half of the eighteenth century, the building of a new and larger church to dedicate it to Our Lady of Mount Carmel also began. A walled-in slab above the portal of the elevation attests that the Carmine Church was founded in 1779. In the late 19th century, as a result of the measures inherent in the subversive legislation of the ecclesiastical axis, the activity of the Carmelite fathers in the city came to an end, the church was expropriated by the state and assigned to the Worship Fund. Instead, the premises of the Convent were given to the City Council, which established the Elementary and Gymnasium classrooms there and then became the seat of the City Hall until it had to be closed due to structural problems and later restored.
