Origin and history

Lagrange Castle is a monument located in the commune of Blaye, in the Nouvelle-Aquitaine region. Although its existence is attested, the available sources do not specify its period of construction or its architectural or historical evolution. Castles in this region, often linked to wine or military history, played a central role in the local organisation.

In Blaye, as elsewhere in New Aquitaine, these buildings could be used as seigneurial residences, defence sites or symbols of power, depending on the times. Their presence generally reflected the economic and social dynamics of their time.
