Chiaravalle abbey was founded in 1135 as a daughterhouse of Clairvaux; it is one of the first examples of Gothic architecture in Italy, although maintaining some late Romanesque influences.
After a series of temporary buildings had been constructed, the construction of the permanent church was begun around 1150–1160; it was consecrated on 2 May 1221. Works continued in the 13th century with the first cloister, south of the church, and, in the 14th century, the crossing tower and the refectory. In 1412 a small chapel was built next to the southern transept. Today it is used as the sacristy.
In 1442 the abbey was placed in commendam. In 1490 Cardinal Ascanio Sforza (the brother of Ludovico il Moro, duke of Milan) commissioned Bramante and Giovanni Antonio Amadeo to construct the Chiostro Grande ('large cloister') and the chapterhouse.
During the Renaissance, numerous painters and artists worked in the abbey: to this period belong for example Bernardino Luini's works. From 1614 to 1616 the brothers Giovanni Battista and Giovanni Mauro della Rovere decorated the interior walls of the church with the frescoes which are still visible today.
When the Napoleonic Cisalpine Republic was founded in 1798, the monastery was partly demolished. What remained included the church, part of the small cloister, the refectory and the entrance buildings. In 1861 Bramante's cloister was destroyed to make way for the construction of the Milan-Pavia-Genoa railway. The abbey remained a private property until 1894, while the Cistercians returned in 1952.
Chiaravalle Abbey is a beautiful temple and well worth seeing, but only for those staying in Milan for over a weekend, otherwise it is too far out to be worthwhile.
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.
