Santa Maria dei Miracoli, also known as the 'marble church', it is one of the best examples of the early Venetian Renaissance including colored marble, a false colonnade on the exterior walls (pilasters), and a semicircular pediment.
Built between 1481 and 1489 by Pietro Lombardo to house a miraculous icon of the Virgin Mary. The plans for the church were expanded in 1484 to include the construction of a new convent for nuns of St. Clare to the east. The convent was connected to the gallery of the church by an enclosed walkway that was later destroyed.
The interior is enclosed by a wide barrel vault, with a single nave. The nave is dominated by an ornamental marble stair rising between two pulpits, with statues by Tullio Lombardo, Alessandro Vittoria and Nicolò di Pietro. The vaulted ceiling is divided into fifty coffers decorated with paintings of prophets, a work by Girolamo Pennacchi's contemporaries, Vincenzo dalle Destre and Lattanzio da Rimini.
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.
