Origin and history

The Salle des Etats de Forez, also known as Salle La Diana, is an emblematic building in Montbrison, in the Loire. Built at the end of the 13th century (4th quarter), it bears witness to the political and administrative importance of the region in medieval times. Its name refers to the states of Forez, a historic provincial assembly that gathered there, reflecting its central role in local governance. The building was thoroughly renovated in the 19th century (3rd quarter), incorporating more recent architectural elements while maintaining its heritage vocation.

Classified as a Historical Monument in 1875, the room embodies the institutional memory of the province of Forez. It is associated with the Maison Latour, another neighbouring building inscribed with historical monuments in 2023, illustrating the continuity of its urban anchoring. Lebrun is mentioned as an actor in its construction or transformation, although the precise details of its intervention remain unclear in the available sources. Today, it houses the Diana Museum, strengthening its status as a major cultural place.

The exact address, rue Florimond-Robertet, and its Insee code (42147) confirm its location in the historic centre of Montbrison. The successive protections (classification and registration) highlight its heritage value, both for its architecture and for its role in regional history. The available data, from Monumentum and the Merimée database, allow to situate the monument with a geographical accuracy deemed satisfactory a priori (level 6/10).
