Origin and history

The farm of the Bonnettes, located in the same name hamlet on the town of Viriville (Isère), is a rare example of 17th century Dauphinian rural architecture. The complex consists of three buildings: a house dating from 1626, a barn from 1643, and a second barn built in the 19th century. These wooden panel constructions, with chestnut frame and oak filled with torchi, and pebble ground floor walls arranged in fish ridge, illustrate traditional Chambaran techniques. The site, perched on a hill overlooking the Bièvre Plain, was fully listed as historic monuments on February 12, 2003 for its outstanding heritage value.

The farm is divided into two distinct parts: the 17th century North Farm and the South Farm, rebuilt in the mid-19th century after the disappearance of the original buildings visible on the 1825 cadastre. The Pisé barn of the southern farm reflects a local architectural evolution, while the northern farm retains unique features, such as its two-paned roof covered with canal tiles. A dendrochronology confirmed the dates of construction of the house (1626) and barn (1643), highlighting their rarity in the area. Today, the farm belongs to a family of farmers who preserve its professional and heritage use, opening the site on Heritage Days.

All the Caps testify to the adaptation of rural buildings between modern and contemporary times. The wood-pan buildings, typical of the Dauphiné, contrast with later pise structures, reflecting local resources (wood, earth, pebbles) and agricultural needs. The transformation of an appentis into a second home around 1739, with a French ceiling, and the removal of another appentis after 1825, illustrate the successive modifications to adapt to lifestyles. The hamlet, still in partial activity, embodies the continuity between heritage and rural life, with animations like cooking in the bread oven during cultural events.
