A church at the site of current San Bartolomeo was present by the 15th century, but the frequent earthquakes that afflict Sicily, including a local tremor in 1693, may have forced the reconstruction of the church to begin in 1752. The facade transitions from late-Baroque to Neoclassical, starting with 18th-century designs by Antonio Mazza, modified later by Salvatore Alì and with the top completed in 1815 by Father Ventura. The iron gate in the portal was designed by Alì in 1822.
The facade presents a triangular front, with columns rising from Doric to Ionic to Corinthian, and culminating in a belfry with a ribbed dome. The roofline houses a statue of Madonna and Child, flanked by two pairs of saints, Peter, Paul del Marabitti, Bartholomew and William.
The interior has a single nave, with a Latin cross plan. The entrance is flanked by tomb monuments of the Micciche family (1631) sculpted by Francesco Lucchese. The church houses a silver processional reliquary/crib, covered in silver in 1862, which housed an icon of the child Jesus, called the Golden Cicidda, and carried in procession on Christmas Day.
In the north transept is arrayed a grand Presepe, or Nativity, (1773-1776) sculpted by Pietro Padula. Of the original 65 statues there are only 29. The backgrounds may be more recent. Adjacent to Nativity Chapel, is the Chapel of the Immaculate Conception with a silver coated statue, made in 1850 by the brothers Catera.
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.
