On the left side it presents the entrance to what were the service rooms of the convent attached to the church and, on the right side, the ancient exterior portico (portaria), with its walled arches, inside which the friars lodged and provided assistance to pilgrims and mendicants. Inside the single-nave church, three chapels dedicated respectively to Our Lady of Remedy, St. Francis of Assisi and the Crucifix (added after 1736 as St. Mary of Mount Carmel) open on the left side. On the left side is an artistic wooden chancel capable of 31 stalls, 23 in the upper semicircle and 4 on each side in the lower semicircle. A wooden pulpit is arranged on the right side of the nave. On the walls of the chancel are niches enclosing the simulacrum of Our Lady of the Angels. In the last restorations around 1980 during the resurfacing of the floor of the Chapel of Our Lady of Remedy, a trapdoor was discovered that via a small staircase of seven steps led to a crypt used as a burial room.
