San Giuseppe church was erected in 1756-1796 under the patronage of the Benedictine order. The church and an adjacent convent of nuns occupied a site where prior to the 1693 earthquake had been located the church of San Tommaso. The architect is unknown, but in the circle of Rosario Gagliardi. Like many local churches, the façade has three highly sculpted order, decorated with statues of Saints of the Benedictine orders, including Saints Benedict and Mauro above and St Gertrude and Scolastica below. Near the entrance are statues of St Gregory the Great and St Augustine by Giambattista Muccio in 1775. The entrance portals have iron grillwork screens (1774) by Filippo Scattarelli.
The interior has an oval layout, but kept a large choir and coretti situated over the entrance and flanking the nave, where the nuns could hear the mass while remaining cloistered. Over the vault is a fresco depicting the Glory of St Benedict with St Joseph (1793) by Sebastiano Monaco. The walls are elaborately stuccoed (1793) by Agrippino Maggiore and the Cultrera di Licodia Eubea. The altars (19th century) have elaborate scagliola, and have altarpieces by Tommaso Pollace and Giuseppe Crestadoro, depicting the Trinity, St Mauro, St Benedict, and Ste Gertrude. The pavement has white stone and maiolica tiles. The Vestibule has statues depicting St Benedict (17th century) and a silver-coated St Joseph (1785).
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.
