Dedicated to St. Benedict of Nursia, the church of San Benedetto was built from April 1334, then it was destroyed by 1693 Sicily earthquake. The church and the monastery were rebuilt between 1708 and 1763 and Giovanni Battista Vaccarini was one of the main architects.
The church was also damaged by bombing in World War II and later restored by the architect Armand Dillon.
Its most famous feature is the Angel's Staircase, a marble entrance stair decorated with statues of angels and surrounded by a wrought iron railings. The entrance door, in wood, has panels with Stories of St. Benedict.
The interior, with a single nave, is home to frescoes by Sebastiano Lo Monaco, Giovanni Tuccari and Matteo Desiderato. The vault and semi-dome were painted Giovanni Tuccari with the History of Saint Benedict and six Allegories surrounding the Triumph of Saint Benedict. The Saint is represented in his traditional iconography, in a festive and cheerful scenario. The high altar is in polychrome marble with hardstone intarsia and bronze panels.
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.
