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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
