Qualche cenno sull'argomento:
Santa Croce church – which rests on the calcareous bastion with the same name – was probably built as a synagogue since its early years after the donation of the Castle to the Pisans (1217), even though there is no irrefutable evidence of it. However, it was certainly a Jewish place of worship when Cagliari – conquered by the Catalan-Aragonese army- became the Capital of the Kingdom of Sardinia in 1326, and hosted a flourishing Semitic community. In 1492 the Jews were expelled from all the States of the Spanish Crown, including the Kingdom of Sardinia, and the synagogue of Cagliari was sealed to become a catholic church consecrated to the Holy Cross immediately after.
Since the XVI Century it was officiated by the Society of Jesus, the religious Order founded in 1534 by St. Ignazio of Loyola. The simple building was expanded during the XVII century following the design of the architect Giandomenico of Verdina. It was completed in 1661 thanks to the generosity of the Brondos, Marquises of Villacidro, as seen from the inscription on the facade under the heraldic shield of the family. In 1773, fifty-three years after the Kingdom of Sardinia went to the House of Savoy, the Jesuits were dissolved by Pope Clement XIV, and the church ended up in the hands of the State until 1809, when King Vittorio Emanuele I gave the building to the Chivalric Order of Saints Maurizio and Lazzaro, and raised it to the rank of Magistral Basilica. The church still belongs to the Mauritians Knights.
