The Venetian Castle was built during the 15th century in Split. Built just south-west of the Diocletian's Palace along the shoreline, the castle had an irregular pentagonal shape with three towers facing north and overlooking the city. The decision to build the castle was made in 1424, however, it wasn't until 1441 that it was actually built on the grounds of a demolished monastery. By the early 16th century, the castle was in poor condition and it wasn't until the first half of the 17th century that work on improving it began.
By the early 19th century, the castle had lost its defensive purpose and the southern walls were demolished between 1806 and 1807 on the orders of Auguste de Marmont during the Napoleonic Wars. Presently, what remains of the castle is the large central tower and the smaller eastern tower with the wall connecting them, both located on the Radić Brothers Square (Trg braće Radić).References:
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.
