The Cistercian Abbey of Alba Ripa, founded in 1135 by 12 monks from Clairvaux, has played a key role in French history, influenced by notable figures.
Built in the typical Bernardine style, it features a church with an east-facing flat-walled chevet, sections for choir monks and lay-brothers, and a communal north wing. Situated in a remote area, the monks mastered water resources, diverting the Aube River for self-sufficiency.
After flourishing in the 13th century, the abbey declined during the 100 Years’ War. It endured religious wars in the 16th century and underwent reconstruction in the 17th and 18th centuries.
Following the dissolution of monastic orders in 1790, the abbey saw industrial and residential use before becoming a prison in 1856, housing female prisoners, including the communard Louise Michel. Later, it served as a reform school and returned to religious use between 1925 and 1960.
The Solvay company owned it from 1960, using it as a holiday camp until 2004.
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.
