The Château d'Écouen was built between 1538 and 1550 by the architect Jean Bullant for Anne de Montmorency, who was made Connétable de France in 1538. Anne de Montmorency had inherited the château in 1515, and his building campaigns were informed by his first-hand experience in overseeing royal works at Saint-Germain-en-Laye and Fontainebleau.
Anne de Montmorency was a major patron of the arts in France, and a protector of artists: his chapel was decorated with sculptures by Jean Goujon, and Jean Bullant, Barthélemy Prieur, Bernard Palissy. Some of the Androuet du Cerceau family found protection and work at Écouen. Unhappily, no building accounts survive, so the precise sequence of the construction cannot be closely followed; panels of grisaille stained glass in the gallery of the west wing are dated 1542 and 1544, and the east wing was paved in 1549-50. The building was frescoed and furnished during the 1550s, in the style of the School of Fontainebleau.
In 1787 the east (entrance) wing was demolished by the owner, the Louis Joseph de Bourbon, prince de Condé. When he emigrated at the Revolution, Château of Écouen fell to the State, as a 'national property'.
Following an idea of André Malraux the castle was thoroughly renovated by architects of the Monuments Historiques, after having served as a school for daughters of chevaliers of the Légion d'Honneur, from 1807 to 1962, in order to house the Musée de la Renaissance, comprising the Renaissance objects of the collections of the Musée de Cluny, in sympathetic surroundings. A series of small, highly focussed exhibitions have been staged at Écouen over the years since the museum fully opened in 1982.
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.
