The rectangular Sponza Palace with an inner courtyard was built in a mixed Gothic and Renaissance style between 1516 and 1522 by Paskoje Miličević Mihov. Its name is derived from the Latin word 'spongia', the spot where rainwater was collected.
The loggia and sculptures were crafted by the brothers Andrijić and other stonecutters.
The palace has served a variety of public functions, including as a customs office and bonded warehouse, mint, armoury, treasury, bank and school. It became the cultural center of the Republic of Ragusa with the establishment of the Academia dei Concordi, a literary academy, in the 16th century. It survived the 1667 earthquake without damage. The palace's atrium served as a trading center and business meeting place.
The palace is now home to the city archives, which hold documents dating back to the 12th century, with the earliest manuscript being from 1022. These files, including more than 7000 volumes of manuscripts and about 100,000 individual manuscripts, were previously kept in the Rector's palace.
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.
