Origin and history

The Château de La Côte-Saint-André, nicknamed "Château Louis XI", found its origins in the 13th century under the impulse of Philippe I of Savoie, who had it built in 1273 to protect the parish from Dauphinian incursions. At that time, the area depended on Savoy's house, and the castle played a strategic defensive role. In the 14th century, after the city joined the Dauphiné, the building became a place of power: the states of Dauphiné gathered there, marking its political importance. However, its decline began in the 16th century: it was destroyed in 1518 by mercenaries who returned from the Italian wars, then damaged during the religious wars, and it fell into ruin and lost its military function.

In the 19th century, the castle experienced a new life when the Marist brothers acquired it in 1869. They raised a floor of the central building and turned it into a religious establishment, before it became a public school after its acquisition by the commune in 1906. Restoration work continued in the 20th century, notably in the 1970s, with the repair of the roof, the chaining of carrying walls and the sealing of the gazebo. These interventions are intended to preserve its architectural heritage, partially classified as a historical monument since 1983 (scenery of honour, Louis XI room, monumental fireplace).

Today, the castle combines medieval heritage and modern redevelopment. Its inner courtyard, with a dome transformed into an auditorium, hosts the Berlioz Festival every year, while its rooms house cultural projects (library, music school). Although the Paradis du Chocolat Museum (1994–2019) has closed, the building remains a local symbol, mixing Savoyard, Dauphinian and contemporary vocation. Its architecture, marked by 17th and 19th century elements (rectangular facade, classified interior decorations), bears witness to the political and religious developments of the region.

The site is also linked to art: the painter Johan Barthold Jongkind, precursor of Impressionism, staying there in 1878, immortalized the city and its castle in watercolours. This artistic dimension, coupled with its role in current cultural events, strengthens its anchoring in the living heritage of Auvergne-Rhône-Alpes.
