The parish of Santa Chiara enters fully into the spread of the Aragonese Gothic style that arrived in 1520 in Padria with the construction of Santa Giulia, by craftsmen, almost certainly Catalan working in Alghero. The Catalan taste is especially noticeable in the gabled facade (divided into two orders by a horizontal cornice) where the portal with a lily arch and other decorations are the result of the diffusion made by local workers who had learned Aragonese styles from those working in Padria. It was built in the 16th-17th centuries and then enlarged in the 18th century, as evidenced by a stone plaque embedded in the rear facade. It has a single nave with side chapels, added later, perhaps, in the following order: those in front on either side of the chancel, formerly dedicated to St. Narcissus and St. Joseph; the one on the right in the second bay, formerly dedicated to the Crucifix and now housing the wooden statue of St. Clare; and the first on the left to Our Lady of Ferragosto. The barrel vault is marked by two pointed arches forming three bays. The chancel, with a quadrangular plan, was rebuilt in 1696 by Bonorvian mason Francisco Tola. A chapel dedicated to souls opens in the first bay. On the right side was the chapel of St. Anthony of Padua, which was removed in the 1960s to widen the street. On the altar side you have the baptismal font, the ambo and on the left side the statue of St. Clare, a wooden work dating back to the 17th century. The church also preserves some noble coats of arms: one shield bears the poles of Aragon; the other, also repeated on the facade, has three small mountains symbolizing the lineage of Serafino Montagnan, the first feudal lord of Cossoine, as well as dancers with a lute player and a beautiful Annunciation.
