The Cathedral of St. James in Šibenik is a triple-nave basilica with three apses and a dome. It is the most important architectural monument of the Renaissance in the entire country. Since 2000, the cathedral has been on the UNESCO World Heritage List.
The building of the church was initiated in 1402, though plans on its construction had already begun in 1298, when Šibenik became a municipality. The actual work to transform the older Romanesque cathedral began in 1431. Built entirely of stone (limestone from a nearby stone quarry and marble from the island of Brač), it was completed in three phases, from 1433 to 1441, when the Grand City Council entrusted the work to local and Italian masters Francesco di Giacomo, Lorenzo Pincino, Pier Paolo Bussato, Bonino da Milano, and Giorgio da Sebenico (Juraj Dalmatinac) and to Croatian ones Andrija Budčić and Grubiš Šlafčić.
Its beauty is especially emphasized by the imposing Renaissance dome, the work of Niccolò di Giovanni Fiorentino, which was damaged in the Croatian War of Independence, and nowadays is a special symbol of Šibenik.
The Cathedral is also known for its iconographic innovations, among which a special place is occupied by sculptures of 71 heads on the outside part of the shrine, the work of Georgius Mathei Dalmaticus, for which scientists are still not quite sure who they represent.
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
