Santa Maria Formosa was erected in 1492 under the design by Renaissance architect Mauro Codussi. It lies on the site of a former church dating from the 7th century, which, according to tradition, was one of the eight founded by San Magno, bishop of Oderzo. The name 'formosa' relates to an alleged appearance of the Holy Virgin disguised as a voluptuous woman.
The plan is on the Latin cross, with a nave and two aisles. The two façades were commissioned in 1542, the Renaissance-style one facing the channel, and 1604, the Baroque one facing the nearby square.
The artworks in the interior include the St. Barbara polyptych by Palma the Elder, one of his most celebrated works. The Conception Chapel houses a triptych of Madonna of Misericordia by Bartolomeo Vivarini (1473), while in the Oratory is the Madonna with Child and St. Dominic by Giambattista Tiepolo (18th century). There is also a Last Supper by Leandro Bassano.
The dome of the church was rebuilt in after falling during an earthquake in 1688.
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.
