Origin and history

Bienville Castle was built in the mid-18th century for Jean-Baptiste Thomassin de Bienville, owner of the local forges. The main building, extended by two wings in return, forms a U-shaped plan. The south wing, the oldest, already appears on a road map of the 1760s, while the north wing, housing a chapel dedicated to Saint John the Baptist, is attested from 1780, marking a second phase of construction in the 18th century. The house body retains remarkable elements such as marble fireplaces and 19th-century panelling.

The romantic park, designed after 1837, illustrates the 19th century landscape cannons. It includes two pigeon trees (including one transformed into orangery), outbuildings, and a garden garden to the west. The gardener's house, dated 1808, completes this ensemble. The facades, roofs, commons, outbuildings, park (with its fence wall) and garden-potager have been protected since 2001 by an inscription in the Historical Monuments.

The castle reflects the architectural and landscape evolution between the 18th and 19th centuries, mixing industrial heritage (forges of Thomassin de Bienville) and romantic aesthetics. Its U-shaped plan, typical of seigneurial residences, and subsequent developments (chapel, park) testify to its adaptation to the uses and tastes of its successive owners.
