The Basilica of the Holy Cross in Jerusalem or Basilica di Santa Croce in Gerusalemme is one of the Seven Pilgrim Churches of Rome. According to tradition, the basilica was consecrated circa 325 to house the relics of the Passion of Jesus Christ. The relics were brought to Rome from the Holy Land by Empress St. Helena, mother of Roman Emperor Constantine I. At that time, the Basilica's floor was covered with soil from Jerusalem, thus acquiring the title in Hierusalem.
After falling into neglect, the Pope Lucius II (1144-1145) restored the Basilica. It assumed a Romanesque appearance, with a nave, two aisles, belfry, and porch.
The Basilica was also modified in the 16th century, but it assumed its current Baroque appearance under Pope Benedict XIV (1740-58), who had been its titular prior to his elevation to the Papacy. New streets were also opened to connect the Basilica to two other Roman major basilicas, namely, San Giovanni in Laterano and Santa Maria Maggiore. The façade of the Basilica, which was designed by Pietro Passalacqua and Domenico Gregorini, shares the typical late Roman Baroque style of these other basilicas.
The relics were once in the ancient St. Helena's Chapel, which is partly subterranean. Here the founder of the Basilica had some soil from Calvary dispersed. In the vault is a mosaic designed by Melozzo da Forlì before 1485 depicting Jesus Blessing, Histories of the Cross, and various saints. The altar has a huge statue of St. Helena, which was obtained from an ancient statue of the pagan goddess Juno discovered at Ostia.
The apse of the Basilica includes frescoes telling the Legends of the True Cross, attributed to Melozzo, Antoniazzo Romano, and Marco Palmezzano. The Museum of the Basilica houses a mosaic icon from the 14th century which, according to the legend, Pope Gregory I had made after a vision of Christ. Notable also is the tomb of Cardinal Francisco de los Ángeles Quiñones sculpted by Jacopo Sansovino in 1536.
Peter Paul Rubens, who had arrived in Rome by way of Mantua in 1601, was commissioned by Archduke Albert of Austria to paint an altarpiece with three panels for the Chapel of St. Helena. Two of these paintings, St. Helena with the True Cross and The Mocking of Christ, are now in Grasse, France. The third, The Elevation of the Cross, was lost. Before his marriage, the Archduke had been made a cardinal in the Basilica.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
