From a letter addressed to the Cathedral Chapter by Bishop Manca de Cedrelles, we know that the Friars planted the cross and laid the foundation stone of the convent and the attached church of St. Mary of the Angels on December 8, 1608. The Capuchins carried out their religious and social activities in the area until 1867, that is, for more than 250 years, until they were forced to leave because the convent and church were expropriated by the state. The entire architectural complex has been restored and will become home to the newly established Archaeological Museum of Bosa and Planargia. The church also underwent changes some of which were unjustified. The facade of the church is divided into two orders by a molded gable. Inside, the temple has a single barrel-vaulted nave, and three cross-vaulted chapels open on the right side. The chancel has been made smaller, making liturgical celebrations more difficult, while the floor of the hall has been raised to the height of that of the chapels, altering the spaces that no longer conform to the style of an ancient church. The small chancel extends into a large apse choir and is lit by a Renaissance-style window. The doorway is classical as is the cornice that runs down the nave and into the chancel. The style of the church is a fusion of Catalan Gothic and the severe Mannerism imported to the Island around the last quarter of the 16th century. Once located in the niche of the high altar, one could admire, the remarkable statue of Our Lady of the Angels holding the Child Jesus holding the globe with the cross embedded in it. Following restoration work in 1982 it was moved to the episcope of Bosa while the remarkable wooden baptistery is in the chapter house in the cathedral.
