Qualche cenno sull'argomento:

The chapel, owned by the Aymerich noble family, lies in via del Duomo, once called Carrer dels Pelliciers (Fur Artisans street) and later Carrer de la Seu (street of the Seat, i.e. the Cathedral). For a long time, the people of Cagliari called it Sa Ruga de sa Speranza, the street where Nostra Signora della Speranza (our Lady of Hope, i.e. the Virgin who is waiting for the birth of Jesus Christ) is celebrated at least once a year. The construction of the church dates probably back after 1535: the Aymerich family’s coat of arms shows a double-headed eagle, granted to the house by Charles V after the battle of Tunis (1535). The church has the usual features of the Catalan-Sardinian architecture. The façade has no ribs or ornamentation, except for the portal, which  has an architrave. The interior is rectangular, covered by three vaults. On the right are three chapels, built after the construction of the church. The story of the church is connected to the Sardinian Parliament, during the Spanish times: the military – or noble – “Stamento” had its seat here. After the Jesuit order was expelled from the island, the church was for a short period the seat of the Congregation of Artists (artisans). The bronze bell on the bell gable was still ringing in the fifties, calling the many faithful to celebrate Nostra Signora della Speranza every 18th of December, especially members of the most important noble families in Castello district, who used to celebrate the Christmas novena in this small church. The church of Hope is currently hosting the services of  Saint Saba’s church – an orthodox church belonging to the Moscow Patriarchate – and has been equipped with orthodox liturgical furnishings.
