Owned by the Secular Franciscan Order, its structure dates back to the 13th century (1271). Its foundation is attributed according to oral tradition to St. Francis of Assisi. It was rebuilt in the first half of sec. XIII from a medieval structure of which elements remain. The Mannerist façade dates from 1635. The entire convent has undergone new interventions throughout the seven hundred. In 1800 the facade of the church was renovated. In the second half of the 19th century, in the convent area, after being subject to rehabilitation works, the Military Hospital was installed and, later, the asylum for the royal duke of Bragança. After the restoration of the church some medieval frescoes were discovered. It was an important point of passage of the route of pilgrims who were going to Santiago de Compostela. Part of the convent is now the District Archive of Bragança and it is possible to visit.
