Royaumont Abbey is a former Cistercian abbey built between 1228 and 1235 with the support of Louis IX. Several members of the French Royal family were buried here (instead of Saint Denis Basilica), for example, three children and two grandchildren of Louis IX.
The abbey was dissolved in 1791 during the French Revolution and the stones were partly used to build a factory. However, the sacristy, cloister, and refectory remained intact.
In 1836 and 1838, respectively, two operas by German composer Friedrich von Flotow opened at Royaumont—Sérafine and Le Comte de Saint-Mégrin.
In the early 20th century, the abbey was bought by the Goüin family who in 1964 created the Royaumont Foundation, the first private French cultural foundation. Today, the abbey is a tourist attraction and also serves as a cultural centre.
From January 1915 to March 1919 the Abbey was turned into a voluntary hospital, operated by Scottish Women's Hospitals, under the direction of the French Red Cross. It was especially noted for its performance treating soldiers involved in the Battle of the Somme.
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.
