Piazza Armerina Cathedral is dedicated to Mary of the Victories (Maria Santissima delle Vittorie). It is the seat of the Bishops of Piazza Armerina.
Built on the foundations of an earlier church of the 15th century and based on a design by architect Orazio Torriani, its construction began in 1604 and ended in 1719, while the dome was added in 1768. It became the seat of the Diocese of Piazza (later Piazza Armerina) when it was created in 1817.
The interior of the cathedral is dominated by the central dome. It contains a cross painted on both sides, showing the crucifixion and resurrection of Christ, and a baptistery by Antonello Gagini.
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.
