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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
