Origin and history
The castle of Dizimieu was first mentioned in 1345, attesting to its medieval origin. At that time, it already included elements typical of the castles, although its detailed description was only available in 1687: a lower room, a chapel, a kitchen, a vaulted cellar, an oven and its outbuildings. These installations reflected its role both residential, defensive and seigneurial, characteristic of the rural fortresses of Isère.
In 1722, the castle's state of advanced degradation led to the abandonment of the old building in favour of an ambitious reconstruction, carried out between 1740 and 1773. However, defective foundations led to its destruction in 1780, reducing the site to a farm. The chapel, built in 1610, was then used as a burial place for the local lords, emphasizing the link between the castle and the nobility of Dizimieu. After 1861, a partial restoration revived some medieval parts, while the entrance pavilions and the East and West towers, which had been protected since 1988, now bear witness to this turbulent past.
The site illustrates the hazards of French architectural history, where destructions and reconstructions succeed each other according to the needs and means of the owners. Its partial inscription in the Historical Monuments in 1988 preserves significant remains, although its overall condition remains marked by centuries of transformation and adaptation, from the status of fortress to that of farm, then of restored residence.
