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.
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
