Santa Barbara church was built in 1757 for the Convent of the Salesas Reales, housing nuns belonging to the order of St. Francis de Sales. The convent was founded in 1748 by the Queen Bárbara de Braganza, wife of Ferdinand VI of Spain. The church, which stood next to the convent, was designed by Francisco Carlier in collaboration with Francisco Moradillo. In 1870, the monastery was closed, and the government used the monastery as the Palace of Justice, now as the Supreme Court. In 1891, the church was open to parish worship.
The exterior is noted for the statues of St. Francis de Sales and St Jeanne de Chantal, founders of the Order, sculpted by Alfonso Giraldo Vergaz. In the interior, are the burial tombs of Ferdinand VI and his wife. These were commissioned by Charles III of Spain and completed by the architect Francisco Sabatini and the sculptor Francisco Gutiérrez.
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.
