The Basilica della Santissima Annunziata del Vastato construction was begun by the Franciscans in 1520 in a site previously occupied by the small church of Santa Maria del Prato, belonging to the Humiliati. Works were however halted in 1537, and in 1591 the Lomellini family continued the reconstruction, directed by Taddeo Carlone.
In the early 17th century the rich Baroque decoration was executed, with Andrea Ansaldo in charge of completing the works, and in particular the dome. The current Neoclassicist façade dates to 1830-1840s, designed by Carlo Barabino. The church was damaged by Allied bombings during World War II.
The decoration was employed the major Baroque studios and artists in Genoa in the 17th century.
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.
