Castelsardo Cathedral is dedicated to Saint Anthony the Great. It became the seat of the bishop of Ampurias in 1503. In 1839 the diocese of Ampurias was merged into that of Tempio, and the episcopal seat moved to Tempio Cathedral, when that of Castelsardo became a co-cathedral, as it remains in the present diocese of Tempio-Ampurias.
The current building dates from the reconstruction begun in 1597 that lasted until the 18th century. The cathedral is a mixture of Catalan Gothic and Renaissance elements, and overlooks the sea directly. The interior is on the Latin cross plan, with a single nave with barrel vaults, side chapels and transept. The crossing has a cross vault on four pilasters with sculpted capitals.
The church has a tall bell-tower, topped by a small dome decorated with majolica.
The presbytery is raised, and has a marble balustrade. The apse, with a cross vault decorated with stars, houses the marble high altar of 1810, characterized by the church's main attraction, the Enthroned Madonna and Child, a painting of the 15th century, attributed to the Master of Castelsardo. Also by the latter artist is a St. Michael the Archangel, displayed in the crypt, now home to the diocesan museum.
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.
